doc test failed even though docs compiled just fine locally.

I suspect it is because the action we are using depends on an earlier version of Sphinx (2.4.4)

When I run

pip install -Iv sphinx==2.4.4

to installed that version, and run make html I get build error:

Running Sphinx v2.4.4

Extension error:
Event 'html-collect-pages' already present
Makefile:20: recipe for target 'html' failed
make: *** [html] Error 2

The action does not seem reliable as it has been more than a year since last update on the repo and it does not have a versioning to ensure stability going into the future. Probably time to revisit the doc check github action so that it doesn't rely on their action.

In any case, I'm sure the action is failing due to a bug in their github action and not our docs
