chore(cibw): productify the cibuildwheel workflow

[vytas7]

Examples of a successful run:

• https://github.com/falconry/falcon/actions/runs/10626781301
• https://github.com/falconry/falcon/actions/runs/10629319023 (latest)

I also bumped the tag to dev2 in order to be able to dispatch a new build to TestPyPI.

Closes #2310.

This needs discussion I think, I did take this into consideration, but haven't added any NOTE yet. Let's discuss this on Gitter/Matrix.
