Change regional language codes (#8065)

* Change regional language codes

According to `ISO-639-1` and `ISO-3166-1 alpha-2` recommendations, regional
languages must be written with the language code in lowercase and the region
in uppercase. For instance, we should have `en-US` instead of `en-us`.

Folders have been updated to reflect those recommendations and regional
language codes have been updated in the translation files.

* Update README files

* Fix configuration for typos

* Revert language order in documentation

* Remove unnecessary code

* Change language configuration getter

* Fix phpstan error

* Fix typo

* Add types

* escape regex

* Move language logic to avoid magic or deprecated methods

* Minor fix on regex
