Add limit to Sphinx < 5.2.0 until autoapi incompatibilities are fixed (#26670)

The new (released 2 days ago) Sphinx 5.2.0 introduced deprecation
for he way properties are documented and sphinx-autoapi needs
to catch-up with it. Until that, we limit Sphinx to < 5.2.0

Tracked in readthedocs/sphinx-autoapi#352
