Docbuild: conf.py does not recognize dev versions of doc requirements #11838
Description
Description
Since I believe #11797 the doc build no longer proceeds if I'm using a development version of one of the doc dependencies.
For example, we have sphinx-astropy>=1.3 listed as a dependency. I've confirmed multiple times that I have this dependency met through my development installation of spinx-astropy which shows its version as 1.4.dev0 which should meet the >=1.3 requirement.
Expected behavior
The docs should build, allowing a more recent development version of one of the dependencies.
Actual behavior
It seems the line
if version not in SpecifierSet(req_specifier):
fails if version is a .devN version. Not sure if that's a bug in packaging or if there's something extra we need to do...

Indeed, it appears to be a matter of simply adding
