Add custom type text/x-php
Add support for text/x-php since file command use text/x-php in debian system

is PR review stuck due to broken automation?
No I think it was stuck due to no one reviewing it. That said, if you look here you see application/x-httpd-php which is already in our data. That article is from 2011 and I am not sure it justifies adding this type.
But file command returns text/x-php for most os in 2025, and some mimetype guessers depend on file command and system's mimetype database.
@wesleytodd I plan to land this PR by next week
