Feat: add sanity check tool

[tom-rm-meyer-ISST]

Description

As a first step of automation I created a sanity checker for the CHANGELOG.md for a specific release:

• check links
• check that versions given for app and chart match the latest in tx helm chart repo
• check links are given for the correct version

Did not yet create it as an action. Might be a further improvement.

Not sure if this should be better put into one of the sig repos like sig-release.

Pre-review checks

Please ensure to do as many of the following checks as possible, before asking for committer review:

• [x] DEPENDENCIES are up-to-date. Dash license tool. Committers can open IP issues for restricted libs.
• [x] Copyright and license header are present on all affected files

Maybe TRG for subcharts needed?

Also currently in TRG 4.05 we use the v prefix. Maybe it makes sense to harmonize that?
