(mini.deps) Update install to work on Git<2.36.0.

Details:
- Option `--allow-filter-submodules` was added in 2.36.0 release.
  Although it was released almost two years ago, it it not a default
  Git version on Ubuntu 22.04, which has 2.34.1.
  This is usable enough OS version to make using that option
  conditionally.
