Action fails with "Cannot delete branch 'master'"

[tsumo]

Hello! First of all - thanks for the action!

I have a little problem. I use this action to update my username.github.io from another repository. Here is a snippet from workflow file.

- name: Deploy
  uses: JamesIves/github-pages-deploy-action@4.1.2
  with:
    branch: master
    folder: dist
    token: ${{ secrets.PAT }}
    repository-name: tsumo/tsumo.github.io
    target-folder: webgl-study
    commit-message: 'webgl-study (${{ github.event.head_commit.message }})'

As you can see I update a single subdirectory in the gh pages repo. It actually works really well, and creates commits as expected, but action itself fails at the end. Here are last lines of the deploy step log

Checking if there are files to commit…
Running post deployment cleanup jobs… 🗑️
Resetting branch and removing artifacts…
/usr/bin/git checkout -B github-pages-deploy-action/73l4ld4xu
Switched to a new branch 'github-pages-deploy-action/73l4ld4xu'
/usr/bin/git branch -D master --force
error: Cannot delete branch 'master' checked out at '/home/runner/work/webgl-study/webgl-study'
Error: The process '/usr/bin/git' failed with exit code 1
Deployment failed! ❌

I don't understand why it tries to delete master branch in checked-out repo, and I don't know why git complains about it.

Ah, this is an issue related to the new version intended to support multiple deployments at once. This is occurring because it's trying to remove the local version of the branch it just deployed to, but it looks like it's your base branch and therefore protected so it can't perform the operation. I'll try and get a fix out for this later today, the deployment should still have gone through, the error is just a false positive. In the meantime you can downgrade to 4.1.1.

This has been released as part of version 4.1.3. You can adjust your workflow accordingly and you will no longer get this error.

Beautiful, works perfectly. Thank you!
