Remove language setting from profile page

Since language switching is now available in the header for all users,
the separate language setting section in the profile page is redundant.

Changes:
- Remove update-locale-form include from profile/edit.blade.php
- Delete profile/partials/update-locale-form.blade.php

Users can now change language using the header dropdown instead.
