This adds the domain of the saved link to the search index in
two formats, the full domain like www.omnivore.app and just
the secondary domain like `omnivore`.
This also adds some ranking to search, making title, description,
and domain more highly ranked than the content but search results
wont change as we still order by saved_at.
Because this is just used to execute the migrations we can
use the non-locked versions here and don't need to pull in all
of the root workspace packages.
