Fix windows tests (git security update)

[Wauplin]

3 git tests are currently failing on the Windows CI with error:

fatal: active post-checkout hook found during git clone:

I seems to be due to a recent git security update that is not yet handled by git+lfs. See:

• Recent Git security releases break git clone on repositories using LFS git-lfs/git-lfs#5749
• fatal: active post-checkout hook found during git clone: git-lfs/git-lfs#5754

In the meantime a solution is to disable this new security feature by setting GIT_CLONE_PROTECTION_ACTIVE=false in the Windows test env. This only affects the CI, not the package itself.

Expectation

CI should be green :)

Merging it now since CI is green + it only affects tests.
