Prerelease CI: Update name, schedule and Python version

[EwoutH]

A bit of maintenance on the prerelease GitHub Actions workflow:

• Rename the workflow to better reflect it's purpose
• Run twice a week (instead of once) on Monday and Thursday early in the morning.
• Set fail-fast to false, so that all jobs finish and don't get cancelled if one fails.
• Run the warnings check test on Python 3.10

I was also wondering, it looks like a warnings.txt file is generated on each run. Should we upload or save that somewhere, or is that already the case?

I will let others better suited to evaluate the pre-release modifications but regarding the warning.txt, yes it's built each time and we test it against a saved version (https://github.com/pydata/pydata-sphinx-theme/blob/main/tests/warning_list.txt). Many surprises came from our dependencies in the past I would advocate keeping it that way

[EwoutH]

Ah so it tracks know warnings, sounds like a smart approach!

Could you enable the workflow to see how it runs?

[choldgraf]

LGTM!

[EwoutH]

Thanks for reviewing! I see two green review checks, anything else needed to merge this?

I just authorized the CI run and we have some failures; @EwoutH can you take a look?

[EwoutH]

This is quite a strange error, could you retrigger the CI to see if it’s CI/network related?

I refreshed the CI and everything run smoothly, I assume the error was network related. As we already have 2 approvals I'm going to merge this one
