[BUG] branch outputs are <PR>/merge rather than the branch name

[chrisjohnson]

Is there an existing issue for this?

• I have searched the existing issues

Does this issue exist in the latest version?

• I'm using the latest release

Describe the bug?

When running the action from a pull_request_review, none of current_branch, head_ref_branch and ref_branch actually include the branch name from the PR.

Here's what I see in the debug output:

##[debug]-e "CURRENT_BRANCH=20/merge" \
##[debug]-e "HEAD_REF_BRANCH=" \
##[debug]-e "REF_BRANCH=20/merge" \

To Reproduce

      - name: get branch name
        id: branch-name
        uses: tj-actions/branch-names@v6
      - name: run thing
        run: |
          docker run \
          --pull=always \
          -e "CURRENT_BRANCH=${{ steps.branch-name.outputs.current_branch }}" \
          -e "HEAD_REF_BRANCH=${{ steps.branch-name.outputs.head_ref_branch }}" \
          -e "REF_BRANCH=${{ steps.branch-name.outputs.ref_branch }}" \
          ...

What OS are you seeing the problem on?

ubuntu-latest or ubuntu-20.04, ubuntu-18.04

Expected behavior?

I'm not sure if my use case (triggering on pull_request_review) just isn't the desired one but my hope would be to have SOME way of consistently getting the branch name from the PR that the review was submitted for

It looks like github.event.pull_request.head.ref includes the right information on a pull_request_review
