This just gets rid of irrelevant packages in the registry. Looking into
which versions aren't needed would require a deeper pass, so I held off
on that for now.
Before, the tests were in the 300-500ms range and now they take
100-300ms.
This did call to my attention that `unrelated` is misspelled as
`unrelateed` but holding off on fixing that to reduce conflicts.
This gives a hint to users that we might not be showing the feature list
for the latest version but the earliest version.
Also when using a workspace dependency or re-using an existing
dependency, this is a good reminder of what the version requirement is
that was selected.
However, when the user or add (the common case) selected a full
precision requirement, this is redundant.
I'm also mixed on whether the meta version should show up.
Fixes#11073
In writing the contrib documentation for functional vs ui tests, I
realized that as we work to make snapbox work for the functional tests,
we'll need distinct `Assert` objects since we'll want to elide a lot
more content in functional tests. I'm making room for this by
qualifying the existing asserts as being for "ui".
