# Workflow to manage bumping the package version and pushing it to the target branch with a new tag.
# This workflow uses a GitHub App to bypass branch protection and uses the GitHub API directly to ensure commits and tags are signed.
# For more information, see this doc: https://github.com/Nautilus-Cyberneering/pygithub/blob/main/docs/how_to_sign_automatic_commits_in_github_actions.md
