Please publish package to PyPI

[ericwb]

Thanks for your work to produce this grammar. Any chance you can also publish the built wheel and tar.gz to PyPI? This makes it easier for other projects to use.

For example, there already exists on PyPI:
https://pypi.org/project/tree-sitter-python/
https://pypi.org/project/tree-sitter-java/
https://pypi.org/project/tree-sitter-go/
