the separated language repository has long been a source of inconvenience and annoyance,
particularly for PR contributors, because having to sync two PRs across different repos
for no reason adds unnecessary friction.
In addition, having the language files separate creates unnecessary requirements for
versioning and branching, which could all be avoided if the language strings were managed
directly in this repository.
This change will make it much easier to do new features that require adding new translation
strings, as well as getting rid of the inconvenience of cleaning up older strings.
Translation updates from Crowdin should also be able to be merged more quickly, since they
will have higher visibility on this repository.
these are noisy and cause conflicts. Since they also usually cause new errors to be reported, we often can't directly update it anyway. Better to test & update this locally.
