fix: linker errors when using in other projects

[nathansbradshaw]

When I was trying to add this tree-sitter to zed, I ran into the following issue

 ld: warning: Could not find or use auto-linked framework 'CoreAudioTypes': framework 'CoreAudioTypes' not found
          ld: Undefined symbols:

          clang: error: linker command failed with exit code 1 (use -v to see invocation)

Removing the comment for the scanner_path seems to fix that build issue when importing this library as a lib into other projects.
