🌱 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.

should we wait to confirm the fix works on CAPI first? or are we confident this works as expected?

I verified that it works.

The important point is to have the same triggers as the linter action to not hit the same case.

And they are now the same except:

• Not having opened --> because there will be no ok-to-test label set
• Adding labeled --> because we want to trigger the approval by this

/lgtm

It makes sense to me - the existing action pretty much works except for not being triggered on updates.
