#9074 - Added support for building sphynx docs using python 3.10+

[j-n-c]

What this PR does / why we need it:

Add support for building Sphynx guides using Python 3.10+

Which issue(s) this PR closes:

Closes #9074

Special notes for your reviewer:

Tested Sphynx version 5.3.0 with Python 3.9.7 and the docs were built successfully. However, chose to add rules for Python >= 3.10 and < 3.10 to ensure backward compatibility

Suggestions on how to test this:

• Install Sphynx requirements while using Python 3.9.x and build guides: Sphynx version 3.5.4 should be installed and build should be successful
• Install Sphynx requirements while using Python 3.10.x and build guides: Sphynx version 5.3.0 should be installed and build should be successful
