🌱 github: add edited and reopened as triggers for the GH workflow approval

[chrischdi]

What this PR does / why we need it:

Adds the types edited and reopened to the triggers for the PR approve GH Workflows action.

Before this PR the golangci-lint action could have been triggered by the edited or reopened actions.
The approval workflow would not get triggered in that case and did not approve the linter.

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
Fixes #9215

I updated the description of this PR: #9251 manually and that correctly approved the workflow run and started the linter.
