Add Brazilian Portugese to localization footer

[brainwane]

https://hosted.weblate.org/projects/pypa/warehouse/#translations says that we're now at 100% translated for Brazilian Portugese. Therefore, let's insert the footer of available locales/translations per #6624, and add Brazilian Portugese.

@yeraydiazdiaz @nlhkabu can either of you do this? Thanks.

I tried editing warehouse/i18n/__init__.py and warehouse/templates/base.html to include Brazilian Portugese:

I think the right locale is pt_BR.

[woodruffw]

I think the right locale is pt_BR.

Yep, this is correct -- Babel's default locale format is cc_lc where cc is the country code and lc is the language code.

[brainwane]

I tried

KNOWN_LOCALES = {"en": "English",
                 "pt_BR": "Brazilian Portugese"}

and got the same ValueError. @woodruffw diagnosed that I might need to clear my cookies because of a _LOCALE_ cookie issue. I used a different browser to visit localhost and did not get the error -- now I see the language chooser (INSTEAD of the sponsor footer). There is no Portugese content when I choose Portugese, probably because we haven't merged any of the new translations yet (they are in #6667).

@woodruffw You were able to find a way to fix this on Thursday night?

Yep, the commits I made to #6747 should fix this.
