chore: use beta-9.1 instead of beta.10

PR Checklist

• Addresses an existing open issue: fixes 🐛 Bug: beta versions should use semver-style dot numeric separator (instead of dash) #5763
• x] That issue was marked as [status: accepting prs
• x] Steps in [CONTRIBUTING.md were taken

Overview

Core issue: beta-9 is reported as greater than beta-10 in semver string comparison, because - is not a proper semver separator. This means beta-10 is never "latest" when beta-9 exists.

To workaround this, settling on beta-9.1, beta-9.2, etc. for the remainder of the v12 betas . Then we will go to rc.1 and rc.2. Mocha 13 will use a normal beta.1, beta.2 approach, but Mocha 12 will suffer from our mistakes :D

Ref backing issue and #5821 as proof :)

This PR also adds some QoL to Release Please workflows for future diagnoses.

To get this PR to work, I manually pushed a new tag:

git tag v12.0.0-beta-9.1 v12.0.0-beta-10
git push origin v12.0.0-beta-9.1

Release Please reads git tag data, not just previous release commit data.

I just realized we'll need to change beta-10 to beta-9.1 and start using beta-9.2 and beta-9.3. What a mess. @copilot help

Done in commit a4ecc77. Updated manifest.json, package.json, and the CHANGELOG.md header to use 12.0.0-beta-9.1 instead of beta-10.0. Future releases can continue as beta-9.2, beta-9.3, etc.

You'll also need to manually push a tag pointing beta-9.1 at the same commit as beta-10:

git tag v12.0.0-beta-9.1 v12.0.0-beta-10
git push origin v12.0.0-beta-9.1

Ref Release Please run 284 which should actually work maybe

Ready for review :)
