@sappelhoff ready for CI branch protection rules to be updated and merged

Do we still support MNE 1.0? Latest stable is 1.2, I don't think we're even testing with 1.0 and 1.1 anymore, right?

[sappelhoff]

+1 to upgrade to MNE 1.2 ... I tried to remove the scipy upgrade in 72bef09 because I felt like it should pass regardless ... apparently I was wrong.

I can take this over tomorrow, thanks a lot @larsoner

[hoechenberger]

Oh I didn't realize we actually still test with MNE 1.0 -- but neither with 1.1 nor 1.2 (which were only implicitly covered for a while when testing with main)

+1 for bumping this to 1.2

[hoechenberger]

Thanks @larsoner, seems I missed quite a few there!!!
