fix(fetch): Replaced php short tag with <?php in fetch latest script.

Fast CGI running on Nginx does not support short tags by default, and this is typically not a setting that can be set at runtime. It's simpler to remove the requirement in code rather than force every environment's php config to support short_tags.
