Remove grep-based static tests from test-update-analysis-as-a-service

[nils-werner-sonarsource]

Summary

• Remove the static-tests job from test-update-analysis-as-a-service.yml — it only grepped for string literals in YAML files, which adds friction without covering real behavior (unit tests do that).

The grep for @master was also fragile on v1 where refs are pinned to the release SHA, causing a spurious failure after every release.
