Thanks @saleem-latif.

Please test on your fork and let us know if the configurations are working.

Semi-outdated instructions are here: https://docs.openedx.org/en/latest/developers/how-tos/enable-translations-new-repo.html it should give you a good idea where to start.

@OmarIthawi I did not add make pull_translations because we won't be pulling translations here as this repo only contains NPM packages. Let me know if openedx-translation flow require that command.

I have done some testing on my fork, here is the action that ran https://github.com/saleem-latif/openedx-translations/actions/runs/9250930503
It did not run merge-translations step but everything worked correctly. Let me know if there is anything else that needs to be tested as well?

Looks great! Thanks @saleem-latif!
