[issue40204] Docs build error with Sphinx 3.0 due to invalid C declaration

[Karthikeyan Singaravelan]

The sphinx version is not pinned in 3.7, 3.6, 3.5 and 2.7 branches too for Doc/Makefile that can cause error on someone trying it out locally. They are pinned in .travis.yml and .azure-pipelines configurations.
