MNT: Use hash for Action workflow versions and update if needed

[pllim]

As recommended by https://scientific-python.org/specs/spec-0008/#pin-github-actions-release-workflows-to-their-full-release-commit-shas , this PR changes your Actions workflow version pins to hashes, and updates to latest release hashes (at the time of writing) if needed.

This is an automated update made by the batchpr tool :robot: - feel free to close if it doesn't look good! You can report issues to @pllim.
