Improve release process

[Sander3003]

In order to share new functionality we need to communicate that to the public.

Reasons to share CoMPAS suite releases:

• Services depend on each other (e.g. some services might not be compatible)
• Not all end-users are interested in seperate updates (if they are, they can always do that)

How to share a release:

• Create a Github action to automaticly get the release notes from all services updates; Store this in the github tag and make a github release
• Write some manual release notes
• Update changelog.md to refer to the github release
• Automate plublications (e.g. Linkedin, slack etc)
