This PR addresses these issues with localized groups / tabs with Postgres / SQLite: - Array fields inside of localized groups. Fixes https://github.com/payloadcms/payload/issues/8322 - Select fields with `hasMany: true` inside of localized groups. Related to 1, but still needed its own additional logic. - Relationship (non-polymorphic / non has-many) inside of localized groups. Previously, even just trying to define them in the config led to a crash. Fixes https://github.com/payloadcms/payload/issues/8308 Ensures test coverage for localized groups.
