Testing on pre-release (beta) versions of Python

[DeeDeeG]

Hi, folks.

I had the idea to test on upcoming Python versions before they become stable.

Current results (Python 3.13): I'm happy to share that Python 3.13 Alpha 2 and master branch of gyp-next seem to be working okay together, at least at the time I'm writing this:

• https://github.com/DeeDeeG/gyp-next/actions/runs/6983988623/job/19006047778
• https://github.com/DeeDeeG/gyp-next/actions/runs/6984119046/job/19006416991

Suggestion: If folks here want, I'm sure it wouldn't be too hard to modify the test matrix of the "Python tests" workflow to run against the prerelease Python version on a schedule, perhaps once weekly, or once monthly?

Let me know if this is something you are interested in, and I can look at the cleanest way to implement it into the workflow .yaml for CI. (Easiest thing would be to just add 3.13 to the test matrix now, and test every PR/push against it, I suppose.)

We should wait for beta versions and then add them to GitHub Actions as we have done in the past.
