[Feature]: Support PHP language #88

Problem or Motivation

I would like to enhance this tool with support for PHP language.

It will require a bump/change in tree-sitter from 0.24 to 0.27 and change of wasm source to more maintained fork - @repomix/tree-sitter-wasms.

I am willing to do those changes. Opening an issue to gather feedback and track progress.

Proposed Solution

Create basic unit tests for languages that don't have any so dependency change does not break anything.
Bump dependencies.
Introduce parsing rules.
