L3 - Default AT:
- A new endpoint is available to load what's new markdown files (English, German)
- the markdown files are expected in the existing localization folder alongside the localization json files
- if there is no markdown file for a requested locale available the markdown for the default locale is returned instead
- on startup it is validated that a localized markdown exists for every configured locale
- there is no validation of the file content itself as markdown is rather less strict to determine something as invalid
- The new endpoint is documented in confluence
- The Minor Release guide is extended with a step to prepare the whats new content for a minor release
