Running `git checkout CPYTHON_CURRENT_COMMIT` and then `git checkout -c` can render the sphinx build slower because many sources may seem out of date.

Rationale: * Sometimes Sphinx is slow and it's nice to have progress indicators while it's running * If there's a warning or error, it may be possible to get relevant context

So they use the Sphinx required from our branch, not the Sphinx from another random branch. Fixes: #1556
