fixes https://github.com/spesmilo/electrum/issues/8323
from issue:
> Currently, translatable strings from QML are assigned a `context`
> by `lupdate`, which is then also used by the conversion to `gettext`.
> This `context` must be used when translating such a string. This results in
> strings that are unique to QML to not be translated, due to a missing
> `context` parameter which we do not take into account in electrum.
The option "brasilian" is inaccurate since we brazilians do speak Portuguese.
We don't consider "brasilian" as a language, so I believe this change I've made is a more accurate option for this public.
