Translation mismatch for pt_br message

[anaschwendler]

When running django-admin makemessages --all I faced the following issue:

It is possible to run as django-admin makemessages --locale=pt_br but we need fixing anyway :)

Thanks!

I suspect this is a problem with django looking at the LANGUAGES setting for its locale names.

https://docs.djangoproject.com/en/5.0/ref/settings/#languages

With Brazilian, the language code that needs to go in the setting is pt-br, but message catalog creation uses locale name which is pt_BR.

This would need an investigation of how the --all flag is handled.

I'll take a look once I finish the other one for sure :)
