Bump https://github.com/astral-sh/ruff-pre-commit from v0.15.8 to 0.15.12 in the pre-commit group by dependabot[bot] · Pull Request #2140 · gitpython-developers/GitPython

The Windows CI jobs for PR 2140 failed in
test/test_index.py::TestIndex::test_index_mutation. The failing checkout path
creates my_fake_symlink and Git for Windows 2.54 reports a symlink warning
before GitPython raises GitCommandError. This is the same unsupported Windows
symlink behavior that the test already marks as an expected failure when
core.symlinks is true.

Detect Windows hosts that can create symlinks directly and include
GitCommandError in the expected failure types, so symlink-capable Windows
runners do not fail this unrelated Dependabot PR.
