Moving `webtypy` to the Pyodide organisation on PyPI

[agriyakhetarpal]

Hi! We recently applied for an organisation on PyPI, and our request was granted yesterday: https://pypi.org/org/pyodide/

We've also moved all of the maintained (and unmaintained) projects we have to the organisation, and I was wondering if you would be open to moving webtypy to it as well, given that it already exists in the Pyodide organisation on GitHub. Of course, you would retain ownership of the project and all your existing permissions.

Happy to hear your thoughts!
