[5.4] Adding missing locales to Translation MessageSelector

[jn-jairo]

Translations in the format below were returning the wrong plural with locales like pt_BR, because it does not find the locale in the getPluralIndex and always returns the default 0.

'apples' => 'There is one apple|There are many apples',

echo trans_choice('messages.apples', 1);
// There is one apple

echo trans_choice('messages.apples', 0);
// There is one apple

Should this not target master branch ?

useless break

wbr should be after wa_BE

@lucasmichot Thanks for your review.

I don't know if it should target the master branch.

I'm using the version 5.4 and the trans_choice is not working for my locale pt_BR, so i fixed it, and target the 5.4 branch because I need this fix in the version 5.4.

If I need to target the master branch, I can do it, I just need to be sure that the master branch is the correct to make this change applied to 5.4 too.

5.4 is fine. It's basically a bug.
