[Tails-l10n] Tails apps and GUI in weblate

Fellow translators:


The translations for the Tails graphic interface and other programs used to be done
in Transifex, as the other translations in the Tor Project.

I hope you will be happy to know that now this translations can be done in weblate!

They are hosted in https://hosted.weblate.org/translate/tor/tails-gui/

We still need to pass the reviewing capabilities, as there are almost no reviewers in weblate yet.
