Add numpy to system import tests (#2380)

Installing and importing numpy tests for two cases:

* The python architecture and the package architecture don't match
(https://github.com/astral-sh/uv/issues/2326)
* The libc of python and that of the package don't match on linux
(musllinux vs manylinux, picking a compatible manylinux version)

All pylint deps are py3-none-any, so they don't catch those cases.
