Fix translation registration for admin interface

[mlwilkerson]

This fixes the problem reported here.

the JavaScript translations on the admin settings page (admin.php?page=font-awesome) are not being applied, even when translation files are properly installed via wp language plugin install font-awesome ja. The page always displays in English regardless of the site locale.

The fix:

Ensure wp_set_script_translations( ‘font-awesome-official-admin’, ‘font-awesome’ ) is called immediately after wp_register_script() or wp_enqueue_script(), before the script is printed. Moving it to the admin_enqueue_scripts hook alongside the script registration should resolve the issue.

There are some development environment tweaks that made my new dev environment work for making the fix.
