Remove platform gevent requirements

They make it impossible to resolve dependencies on Python 3.13 because
gevent 23.9.0 doesn't have wheels for it.
This special case was, as far as I can tell, somehow ignored in our CI.
By this I mean that even on windows build it used newer gevent. Because
of that, removing those cases shouldn't break anything.
