Upload 1.7.2 docs

[tylerjereddy]

For now I'm delaying the build/upload of the SciPy 1.7.2 docs because:

1. The doc theme means that this will guarantee that we break intersphinx/other links, get an avalanche of issues/waste time triaging those, and then eventually patch some of them with manual work by one of two maintainers on the doc server
2. We're just releasing our first wheels for 3.10, so would be good to focus on any issues related to that before breaking the docs upload again

What about if we merged this repo with scipy.org? Do we need to have this other space?

We should have the same theme and not deal anymore with NumPy.

+1 for delaying doc upload. there are no interesting changes in the docs anyway

Yes we should do that.
