Update Git for Windows to 2.48.1

[tianon]

It's been a while since we updated this, we probably should (and maybe more often; perhaps automated). 🙈

Of course, quite notably, I'm not comfortable merging this right now thanks to docker-library/official-images#18435 (comment):

The problem is that the windows-2025 runner is too old to run the mcr.microsoft.com/windows/servercore:ltsc2025 image released this week (actions/runner-images#11582).

🙃 😭

perhaps automated

If we use our current automation, this will be updated without being tested (because testing Windows is a blind-spot in our current automation until it pushes the commit and GitHub does a test).

Close/open to retrigger GitHub Actions now that actions/runner-images#11582 is resolved

Yeah, until we include Windows tests in our automated update.sh job we should not do it there. Maybe automated PRs to have GHA run the test builds. Perhaps that would just be the git updates and not replace the auto-committed go version bumps of the update.sh job.
