Motivation:
Step failures should be reported by the netty project bot instead of the
github actions bot. We should also prevent steps from triggering from
future label changes by having the workflows remove their triggering
label once they're done.

Modification:
- Make errors be reported through the PAT token so they show as being
from the netty project bot.
- Make the workflow remove the triggering label if it succeeds in
creating a back/forward port PR.
- Only attempt to delete the porting branch on failure, if a porting
branch was created.
- Only report errors for steps that actually failed, i.e. don't report
errors for steps that were skipped due to earlier failures.

Result:
More robust experience with automated backporting.

(cherry picked from commit 85d50c6)
