mysql_secure_installation didn't disable unix_socket authentication

Unix_socket authentication has been installed and enabled by default since MariaDB 10.4.3, and when run mysql_secure_installation, we still get the question "Enable unix_socket authentication? [Y/n]"

I think the question must be changed to "Disable unix_socket authentication? [Y/n]" or at least when press n instead of skipping, the script remove unix_auth from the root user.
