#39675: Remove unnecessary admin notification about deprecated `WPLANG`

----------------------------+-----------------------------
 In `wp-admin/options-general.php` a notification is shown to admins if the
 deprecated `WPLANG` constant is defined. @ocean90 brought up the
 possibility of removing this check while discussing #39207.

 In my opinion the admin notice can be removed, since a regular
 `_deprecated_argument()` notice is already thrown for developers. While we
 generally expect the admin to do some tweaks to `wp-config.php` in a few
 areas, I think this notice is something that could easily confuse non-
 technical users.
