Typo in Root_Environment.php

It was Wordfence flagging it but I checked the file itself and the typo is there.

public static function delete_plugin_data( $config ) {
    global $wpdb;

    $license_key = $config->get_string( 'plugin.license_key' );
    if ( ! emtpy( $license_key ) ) {
        Licensing_Core::deactivate_license( $license_key );
    }

Thanks! I’ll just edit the file manually as there are no other implications.
