chore: Remove sub-copy from Artwork Saved tooltip for auction lots

[oxaudo]

This PR resolves https://artsyproduct.atlassian.net/browse/EMI-1976

My first PR in Eigen so please excuse my mistakes here. Figuring out this Eigen flow!

Description

Ideally we would have the auction saves(watches) go into a different list type but that is not done this way now. We are relying on checking if the artwork is in the auction for handling those saves in several places. So for now just reading this attribute from artwork and basing the sub-copy on that parameter.

Meta: on pr checklist for the checkboxes you should just fill with an x like so [x] or not fill instead of yes or na, for the changelog, you should add a line describing your changes to the applicable section in this case that would be Cross platform user facing changes and could be something like: remove subcopy for artwork save tooltip in auction lots - oxaudo
