Version dropdown links on custom domain are wrong

[evetion]

It seems the version picker doesn't handle custom domains correctly, and always produces root/version links, instead of (in my case) root/repo.jl/version. Demo here: https://www.evetion.nl/GeoDataFrames.jl/dev/

The following code is used to generate the base url:

const getBaseRepository = () => {
  if (typeof window === 'undefined') return '';
  const { origin, pathname } = window.location;
  if (origin.includes('github.io')) {
    const pathParts = pathname.split('/').filter(Boolean);
    return `${origin}/${pathParts[0] ?? ''}`;
  }
  return origin;
};

It seems the function should remove improve the check for github.io.

Whatever will be changed, it should be checked to not break all of the working examples of the version picker with custom domains, e.g., https://lux.csail.mit.edu/stable/ or https://docs.hecke.thofma.com/stable/.

[evetion]

Certainly! The assumption seems to be that GitHub has a repo part, and custom domains don't (as in your examples). Maybe the deploy url should just be taken into account, instead of parsing the current window url.

edit: Although using deploy url broke the website for me 😅

I have made some changes to this on my branch #246 because I wanted to check everything was working on my fork which automatically uses my account's domain. We could also pull those out of that PR to have things separated better.
