chore: add a Windows test on long path with git

[lemeurherveCB]

This PR adds a test to ensure git can works with long paths on Windows.

In draft until a new Git for Windows version is published to fix long paths.

From git-for-windows/git#5550 (comment):

<...> the next Git version, v2.50.0, is planned for June 13th, 2025, and traditionally Git for Windows follows that release cycle.

Ref:

• Windows agents failing to clone Git (LongPathsEnabled disabled) jenkins-infra/helpdesk#4574
• Git fetch fails with too long branches since 2.48.1 git-for-windows/git#5476 (comment)
• Seems fixed in fixup! mingw: support long paths git-for-windows/git#5550 (no release yet)

Testing done
