Message:

I18N: Add the get_available_languages filter.

Sometimes, a language file may not exist in exactly the format or location that get_available_languages() expects it to be in - for sites with this level of customisation, they need to be able to add their own language files to the list of those available.

Props yoavf.
Fixes #38788.
