### What?
This PR fixes an issue where the `join` field table was not respecting
the locale selected in the admin ui localizer.
This also introduces an e2e test to the existing suite to catch this
issue.
### Why?
To properly render `join` field table data according to chosen and
configured locales.
### How?
Threading `req.locale` through to the `payload.find` call in
`buildTableState`.
Fixes#11134
