Remove unused docs bcond

Sphinx 3 was available for years now and nobody bothered to turn this on.
I've tried enabling it and it doe snot work out of the box.
Instead of fixing this, i think we should just drop it.
There were no user reports about missing documentation
and packaging the HTML docs with bundled JavaScript and CSS properly isn't easy.
