Bump sphinx and sphinx-autoapi (#26743)

The sphinx-autoapi bug readthedocs/sphinx-autoapi#352
has been resolved and 2.0.0 version has been released. Since we
are using sphinx/sphinx-autoapi only for `doc` extra, we can
safely bump the minimum version of both to latest released minor
versions.

(cherry picked from commit 9e06c99f6102d0227c6e7b20b258d628c2bc6d5c)
