### 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`.
