[drcgjung]

WHAT

Incorporate mitigations from static code analysis.
Improve workflows
Improve maven build to include Legal Infos
Remove redundant and wrong COPYRIGHT
CHANGELOG prepared for release

WHY

results from mitigating all SAST findings which should not be accepted.
SNAPSHOT charts should be able to find a SNAPSHOT or latest image in dockerhub.
trivy step was disabled/muted due to docker manifest check requiring a login.
maven resources where not completely covering TRG7.05
CHANGELOG needs to reflect the (upcoming) release status.

FURTHER NOTES

Closes #22

Hi @drcgjung, the changes look good to me, but could you check why the tests are failing?

Hi @drcgjung, the changes look good to me, but could you check why the tests are failing?

I puzzled over this myself. But I found it out ... We use a quite stable public SPARQL server (query.wikidata.org) to test "real" internet remoting (and security restrictions). That service seemed to be down in that very moment. Wen I tested myself short term after, it was there again. Maybe just a routing prob inside the github/MS cloud ... Never occurred before and I would only think over the test design if this happens again.

Could you please restart the failed build? Should run through then. Thx.
