Recreate reviewer teams in weblate

It seems we cannot recover the reviewer teams after weblate's termination, so we need to recreate this teams.

Each language should have a reviewer team, and each of this teams should have Adriano from Localization Lab as a member with the ability to add more members.

We should also make a call to reviewers, asking them to contact Adriano or me if we take long to restore they reviewing privileges.
