Allow prereleases from prepare-release workflow

Unfortunately untested, as it is only available once it lands on main.

Fix #7551

@nicoddemus What are your plans on this? If we want a 7.0.0rc1 (or 6.3.0rc1), we should probably get this in first.

[nicoddemus]

Argh completely missed this one.

I'm not sure I will be able to get to this today (I'll do my best), but if anybody wants to take this please go ahead. 👍

[nicoddemus]

Applied @asottile's suggestions. 👍

LGTM now! Fingers crossed that it won't fail in some way which is totally obvious in hindsight but we all missed somehow 🙈

Heh ditto! 😁

Hmm wait, I think this is only a part of the equation, though? At least according to RELEASING.rst we're still triggering @pytestbot via a release comment (rather than triggering the workflow manually), so release-on-comment.py would need an update to support something like a @pytestbot please prepare [major] prerelease from ... too, no?

Those are not up to date, we have made the last two releases (or so) with this new workflow, I think we can remove the release-on-comment one as obsolete. 👍
