Remove windows xfails

[ricardoV94]

Tests were passing locally on my machine, just a sanity check that they still fail here

It seems they are passing. Somehow the strict XFAIL was not triggered?

Closes #4904

In pytest they have spaces around the = sign: https://github.com/pytest-dev/pytest/blob/main/pyproject.toml#L22

Surprisingly enough the strict was raising when I tested locally one at a time
