@garezana - terribly sorry for taking so long on this. I've been meaning to do some fancy rebasing work to remove all of the extra history (moving, deleting, adding again) but I haven't gotten around to it. Would it be possible for you to submit a new PR with either:

1. A single commit for each set of translations (1 commit/topic) that has a meaningful commit message (e.g., "Add spanish translations for dplyr exercises".

or

2. A single commit for all of the translations with a meaningful commit message.

Once you do that I'll get these merged and then working on getting the code working to integrate these translations into the website.

If you want to do the rebasing yourself we can find some time for me to walk you through the basic idea, but the easiest way to do this (especially since there are conflicts now) is to copy files over into a second copy of the repository with a fresh branch off of main
