In [57516], the just-in-time translation loading logic was enhanced to support cases where only `.l10n.php` translation exist but no `.mo` or `.po` files. This caused a slight regression in `get_available_languages()`, which uses the list of files to populate the language dropdown list on the settings page. To address this, the new file extension is now properly stripped off, and the resulting file list is de-duplicated. New test files are added to allow the existing tests to cover this new scenario. See #59656. Fixes #60553. Built from https://develop.svn.wordpress.org/trunk@57639 git-svn-id: http://core.svn.wordpress.org/trunk@57140 1a063a9b-81f0-0310-95a4-ce76da25c4cd
