`skip-github-pull-request` not adding tag or creating release

TL;DR

Disabled pull requests from being created using the input variable skip-github-pull-request: true.
Action fails to do anything to the main branch.
Action fails to create a release.

It's entirely possible this is desired behaviour, but the action isn't creating a release either despite the explicit skip-github-release: false.

If there's no scope for this project to skip the pull requests but also keep making releases/pushing tags please close this issue.

Expected behavior

Expected the action to:

Clone the repository
Do the version bumping based on the last merged pull request message prefix
Push the tag back to the main branch without needing the release pull request phase

Additionally, but optionally, creating the github release at the same time if desired.

Observed behavior

The action is triggered successfully on PR being merged but no mutation of the repository is observed.

Additional information

Previous builds have been success with skip-github-pull-request: false flag being left as default, to explain why there's values up to v0.0.9.

I am using a PAT to avoid the github limitation of not triggering subsequent jobs using the default GITHUB_TOKEN to write back to the repository.

The PAT has full repository read/write, and package write scopes.

This is an attempt to remove the release PR part of the workflow but retain the other part of the functionality, namely creating tags automatically on commit message prefixes being pushed to main.
