Rely on Carpentries' sandpaper translations

[Bisaloo]

The Carpentries now provide the Spanish translation out of the box so we no longer have to provide our own, ensure it's up to date, etc.

This PR now install sandpaper from a simpler branch that only include the fix to install packages from GitHub.
