Sasha 9069bd3fac fix(db-postgres): sort by localized fields (#8839)
### What?
Fixes https://github.com/payloadcms/payload/issues/5152 issue related to
sorting by a localized field with SQLite / Postgres database adapters.

### Why?
It was an incorrect behaviour.


### How?
Modifies the `getTableColumnFromPath` file to have correct join
conditions. Previously if you had this structure in the _locales table
_locale title parent
en          A    1
es          B     1
we sorted by everything that's here, but we need to sort only by the
passed locale.

Additionally fixes a typescript error in `dev.ts` that I added here
https://github.com/payloadcms/payload/pull/8834

Also, removes the condition with `joins.length` in `countDistinct`. It
was there as for this issue
https://github.com/payloadcms/payload/issues/4889 because sorting by a
localized property caused duplication. This can simnifically improve
performance for `.find` with nested querying/sorting on large data sets,
because `count(*)` is faster than `count(DISTINCT id)`
