cppcheck failing in PRs

[forgottosave]

Description

The cppcheck in the CI always fails when executed through PRs. This seems to be a known issue with the cppcheck-action used in the CI and was reported in this issue: deep5050/cppcheck-action#49

Tasks

• either change the usage of the Github action to a self implemented cppcheck execution (or another action)
• or just wait for the action to be fixed / post a PR fixing it (if possible)
