Allow to editing the lang team name; or change pt_BR team's name
Currently, the Language-Team is automatically set according to language name, but the translator might want use a different name. In my particular case, I've been using Brazilian Portuguese as language team name for years, but the GNOME Translation Editor sets to Portuguese - Brazil.
When translating for Translation Project, this is a problem for me as the TP-robot (which perform several checks on the .po file before accepting and storing it) evaluates the Language-Team and returns error with message "language-team incorrect".
Alternatively, if that's too much ask, consider at least renaming the language team name Brazilian Portuguese (in src/gtr-languages.ini
).
