Revert "CI Windows: use action to install CUDA"

This reverts commit 499ccb9.

Although using the action may have some advantages, it also has some
glitches, namely the run when CUDA is not found in cache, it fails, which
is annoying. Also caching doesn't see to exhibit significant advantage
because chocolatey downloads the installer in 30 seconds, anyways.
