ext/standard: Minor improvements to phpinfo() output (#13371)

- Change `http://` links to `https://` for php.net and zend.com
 - Remove `<img border=0` attributes as they are no longer in the HTML standard
 - Replace `<font>` tags with `<span>` tags (used for highlight.* INI color value display previews)
