Pull request created in a GitHub action does not trigger workflows with pull_request trigger
See: #87

Needs to investigate - maybe related to https://github.com/orgs/community/discussions/65321 and/or https://github.com/orgs/community/discussions/57484

When you use the repository's GITHUB_TOKEN to perform tasks, events triggered by the GITHUB_TOKEN, with the exception of workflow_dispatch and repository_dispatch, will not create a new workflow run.

If you want to run workflows from those events, you'll need to provide a PAT.

It's resolved via #89 by using PAT instead
Result: #90
