tree-sitter-php-abc

This is a thin fork of tree-sitter-php providing Atom Backwards Compatibility. At the time of this writing (Sept '21), Atom only supports tree-sitter 0.17, but tree-sitter-php is released against 0.19+. This just rebuilds it against tree-sitter 0.17 so that it can be used in Atom, and specifically in language-php
