Use Unicode CLDR identifier for Brazilian Portuguese

[carlwgeorge]

While packaging this extension for Fedora, rpmlint warned me that pt-br was an invalid locale directory. After some investigation, I confirmed that the Unicode CLDR standard for this is pt_BR, not pt-br. Other GNOME software and extensions also use the pt_BR identifier.

@carlwgeorge - the main branch is just for GNOME 45. Let me know if it needs to be in 44 too

For my Fedora packaging purposes, I'm happy with GNOME 45 and up (Fedora 39 and up), so main should be fine for now. If a user later requests it for GNOME 44 / Fedora 38, I can send the equivalent PR to the gnome-44 branch. Thanks!

Sounds good. I am assuming you are not waiting on anything from me for your packaging. And is there a link I can add to the readme?

[carlwgeorge]

You are correct, the package review was completed a few days ago and I already pushed the first packages. For the readme I suggest using this link, which has a nice overview with links to the builds, updates, bug reports (for the package specifically, which I'll forward up here when appropriate), package sources, and more.
