[PATCH] github-ci: update macos jobs to macos-15

[Junio C Hamano]

GitHub from <no-reply@github.com> address keeps sending

  Subject: [Action Required] macOS 14 hosted runner image is closing down

and suggests to update to either macos-latest (macos-26) or
macos-15.  As we do not have strong reason to pick one over the
other, this patch picks more conservative choice with hopefully
smaller impact.

I think this is fine if it passes CI.  There's not that much of a
difference in terms of POSIX-related functionality in different versions
of macOS, so upgrading to macOS 15 shouldn't be a problem.  I think 15
is a better option than 26 because we're more likely to avoid anything
new that older versions don't have.
