Support pull_request_target event in same way as pull_request about metadata-action

[mithro]

The issue seems to be that;

• for pull_request you get a GITHUB_REF=refs/pull/4/merge
• for pull_request_target you get a GITHUB_REF=refs/heads/upstream-main

@mithro Filtering on pull_request_target event name and using the event.number lgtm in this case.

I have a hack at mithro@15f1e09

[mithro]

Looks like the hack works;

Context info
  eventName: pull_request_target
  sha: d72e4c711d46aca30ac89aed82631c1ae15dd307
  ref: refs/pull/6/merge
  workflow: Build Docker Image for Run DRC for cell GDS (using Magic) Action
  action: mithrometadata-action
  actor: mithro
  runNumber: 52
  runId: 867669317

@mithro You can try with docker/metadata-action@master.

@crazy-max -- I'm still getting a tag for the base branch (IE localhost:5000/run-drc-for-cell-gds-using-magic:main) - Have I configured things wrong or is pull_request_target getting misunderstood as being a branch/tag event as well as a pull request event? Output below;

@mithro

Have I configured things wrong or is pull_request_target getting misunderstood as being a branch/tag event as well as a pull request event?

Yes it's a bug indeed. It seems that the context must be modified to avoid any overflow with the branch events. In the meantime you can do this:

tags: |
  type=ref,event=tag
  type=ref,event=pr
  type=ref,event=branch,enable=${{ github.event_name != 'pull_request_target' }}
  type=sha
  type=sha,format=long

Can you open a new issue about that please?
