Introduce a new function checkGitVersionCompatibility, when the git version can't be used by Gitea, tell the end users to downgrade or upgrade. The refactored functions are related to make the code easier to test.

And simplify the comments for "safe.directory"

>= 1, because there is versionString[:pos-1] below.

But we could use >= 0 and :pos.

That's from old code. I guess it might want to work with 2.3.4.windows and 2.3.4-windows

Right, the -1 is needed for the prefix and therefore i must be >=1.

This seems rather time-critical to get out.

Thank you for reviewing and approving. The backport is done manually : #29157

There is a slight difference in the backport, to try the best to avoid breaking a stable release: bypass the GIT_FLUSH bug there.

Feel free to edit the PR directly if you feel that it shouldn't be done.
