make pip source installs a bit easier

jameslamb commented 3 months ago

updates libucx build requirements so they can be satisfied by only packages from pypi.org
removes --extra-index-url https://pypi.anaconda.org/rapidsai-wheels-nightly/simple/ in pip install calls, now that rapids-build-backend is on pypi.org (https://pypi.org/project/rapids-build-backend/)
sets rapids-build-backend config disable-cuda=true in pyproject.toml
- this means that now pip install . will not require nvcc or produce a wheel with a suffix like -cu12
- *modified CI script used to build wheels to override this, so the published wheels will still have -cu${ver} suffixes
updates docs on source installation to reflect these changes

@vyasr maybe you have to approve too because you've been explicitly asked to review? Not sure to be honest.

@pentschev This was my mistake, we still need a rapidsai/packaging-codeowners review.

I've asked @vyasr offline to to help us with one.

Oh, now I see that. I always miss the grey text. 😅
