Install libnuma on RTD

[jakirkham]

Uses the functionality recently added to RTD in PR ( readthedocs/readthedocs.org#8065 ) by following this example to install libnuma on RTD.

Nice!

JFYI RTD needs to still deploy the change on their end, which is scheduled for next Tuesday afternoon ( readthedocs/readthedocs.org#8065 (comment) ).

Also this feature requires adopting a new RTD config spec version ( readthedocs/readthedocs.org#8065 (comment) ). So have made those changes above and confirmed those work before adding apt packages. The last commit adds the apt packages, which won't work for now, but should work next week (as noted above).

Sure, let's wait for that. Thanks @jakirkham for this! 😄

Looks like RTD has deployed the change. Build is running. Let's see how it goes 🙂

[jakirkham]

Looks like it worked! 🎉

@gpucibot merge

[jakirkham]

I don't think the bot works on this repo yet. So went ahead and merged manually (since it seems like we are ok with the changes)

Edit: If I did missing anything though, happy to revisit in a fresh PR

[pentschev]

Thanks @jakirkham , great work! 😄

RTD shared this as an example use case in their recent blogpost on this new feature.
