Support macos-15-intel ?

[MSP-Greg]

See title.

I assume most people got an email recently announcing it. Run several jobs with JRuby, and the one on macos-13 is 'bang-your-head-against-the-desk' unstable...

Maybe it works already, could you try?

Yes it works: https://github.com/ruby/setup-ruby/actions/runs/18222950554/job/51886938065
So I just need to update the README then and add testing for it.

Sorry for not getting back to you yesterday. Yes, it works.
