Add docs to php.net

[J0WI]

Would be great to have the documentation on a common place like here: https://www.php.net/manual/en/refs.utilspec.image.php

I think the source of this is here: https://github.com/php/doc-en/tree/master/reference

Hi @J0WI,

Sure, that'd be great. It looks like they need docbook, so we'd just need a way to generate that from our existing phpdoc files.

Do you know if that process is documented anywhere?
