HyP3 Cookiecutter v0.5.1

Added

• Added permissions field for every GitHub Actions job in the cookiecutter template, to address ASFHyP3/actions#220

Changed

• Upgraded ASFHyP3/actions reusable actions to v0.18.1.

Removed

• Removed the sync_pr_label input from the call to reusable-release.yml, so that the default value will be used.

Fixed

• Updated README instructions for creating a HyP3 plugin. In particular, added instructions for granting the GitHub user account (e.g. tools-bot for ASFHyP3 repos) sufficient permissions for performing releases.
• The python_version parameter is now provided to reusable-version-info.yml in the test-and-build.yml template.
• Changed the value of the user parameter for reusable-docker-ghcr.yml from {{ cookiecutter.github_username }} to {{ '${{ github.actor }}' }}, to match the example given by the actions README.
