Now that Crowdin is finally working properly, we should add https://github.com/crowdin/github-action as a separate workflow which can be used to update all the translations across the project.
Currently, I am doing it manually by executing the following commands:

crowdin bundle download 4      # for 1.12.2
crowdin download --all         # for the rest

Both can be easily emulated using the Crowdin GitHub action

I went for the semi-good approach to just pull the translations before publishing... Will do sporadic updates to the source here and then, but probably not too much (since we don't need to care about it)
