Check for windows specific site-packages path

[soapy1]

Description

Fixes windows tests, for example https://github.com/conda/conda-libmamba-solver/actions/runs/26194609277/job/77277180835?pr=949

With the latest release of libmambapy (2.6.2) querying for python packages from windows will inject windows specific python_site_packages_path data into results. ref: mamba-org/mamba#4286

This should be a xfail on windows.

Hmm, but mamba-org/mamba#4268 seems to only been in 2.6.x?

yep. The tests run against libmamba 2.6.2

libmamba                       2.6.2                   h06825f5_0       conda-forge
libmamba-spdlog                2.6.2                   hb777e2b_0       conda-forge
libmambapy                     2.6.2                   py310ha763336_0  conda-forge

This is consistent with the project requirements which specify requiring conda-forge::libmambapy>=2.0.0.

Looks like there is already a fix 🎈.

@jezdez looks like there is maybe a new mamba release coming soon #956 🍰

Another approach to make tests pass here is to restrict the libmambapy version to != 2.6.2?

I like the last one, we rarely come back from xfail 😬
