Merge branch 'release/v2023.2'

`mvn verify` already checks formatting, having a separate step is not necessary. We now also check Markdown files for correct formatting.

+
 8. After your modifications are done, push them to your forked repository. This can be done by executing the command `git add MYFILE` for every file you have modified, followed by `git commit -m 'your commit message here'` to commit the modifications and `git push` to push your modifications to GitHub.

+# Multi language support in WebGoat
+
+WebGoat is mainly written in English, but it does support multiple languages.
+
+## Default language selection
+
+1. Current supported languages are: en, fr, de, nl
+2. The primary language is based on the language setting of the browser.
+3. If the language is not in the list of supported language, the language is English
+4. Once logged in, you can switch between the supported languages using a language dropdown menu on the main page
+   1. After switching a language you are back at the Introduction page
+
+## Adding a new language
+
+The following steps are required when you want to add a new language
+
+1. Update [main_new.html](src/main/resources/webgoat/static/main_new.html)
+   1. Add the parts for showing the flag and providing the correct value for the flag= parameter
+2. 
+3. Add a flag image to src/main/resources/webgoat/static/css/img
+   1. See the main_new.html for a link to download flag resources
+4. Add a welcome page to the introduction lesson
+   1. Copy Introduction_.adoc to Introduction_es.adoc (if in this case you want to add Spanish)
+   2. Add a highlighted section that explains that most parts of WebGoat will still be in English and invite people to translate parts where it would be valuable
+5. Translate the main labels
+   1. Copy messages.properties to messages_es.properties (if in this case you want to add Spanish)
+   2. Translate the label values
+6. Optionally translate lessons by
+   1. Adding lang specifc adoc files in documentation folder of the lesson
+   2. Adding WebGoatLabels.properties of a specific language if you want to
+7. Run mvn clean to see if the LabelAndHintIntegration test passes
+8. Run WebGoat and verify that your own language and the other languages work as expected
+
+If you only want to translate more for a certain language, you only need to do step 4-8

-## Unreleased
+## Version 2023.2
+
+With great pleasure, we present you with a new release of WebGoat **2023.2**. Finally, it has been a while. This year starts with a new release of WebGoat. This year we will undoubtedly release more often. From this release on, we began to use a new versioning scheme (https://calver.org/#scheme).
+
+A big thanks to René Zubcevic and Àngel Ollé Blázquez for keeping the project alive this last year, and hopefully, we can make
+many more releases this year.
 
 ### New functionality
 
-- New year's resolution: major refactoring of WebGoat to simplify the setup and improve building times.
+- New year's resolution(2022): major refactoring of WebGoat to simplify the setup and improve building times.
 - Move away from multi-project setup:
-  - This has a huge performance benefit when building the application. Build time locally is now `Total time:  42.469 s` (depends on your local machine of course)
-  - No longer add Maven dependencies in several places
-  - H2 no longer needs to run as separate process, which solves the issue of WebWolf sharing and needing to configure the correct database connection.

+  * H2 no longer needs to run as separate process, which solves the issue of WebWolf sharing and needing to configure the correct database connection.
 - More explicit paths in html files to reference `adoc` files, less magic.
 - Integrate WebWolf in WebGoat, the setup was way too complicated and needed configuration which could lead to mistakes and a not working application. This also simplifies the Docker configuration as there is only 1 Docker image.
 - Add WebWolf button in WebGoat
-- Move all lessons into `src/main/resources` 
-- WebGoat selects a port dynamically when starting. It will still start of port 8080 it will try another port to ease the user experience. 
+- Move all lessons into `src/main/resources`
+- WebGoat selects a port dynamically when starting. It will still start of port 8080 it will try another port to ease the user experience.
 - WebGoat logs URL after startup: `Please browse to http://127.0.0.1:8080/WebGoat to get started...`
 - Simplify `Dockerfile` as we no longer need a script to start everything
 - Maven build now start WebGoat jar with Maven plugin to make sure we run against the latest build.
 - Added `Initializable` interface for a lesson, an assignment can implement this interface to set it up for a specific user and to reset the assignment back to its original state when a reset lesson occurs. See `BlindSendFileAssignment` for an example.
 - Integration tests now use the same user. This saves a lot of time as before every test used a different user which triggered the Flyway migration to set up the database schema for the user. This migration took a lot of time.
+- Updated introduction lesson to WebWolf.
+- Added language switch for support for multiple languages.
+- Removed logic to start WebGoat on a random port when port `8080` is taken. We would loop until we found a free port. We simplified this to just start on the specified port.
+- Add Google formatter for all our code, a PR now checks whether the code adheres to the standard.
+- Renaming of all packages and folders.
