Publish bazelisk on PyPi like you do on npm

Currently bazelisk is helpfully published on npm according to the readme;
```
Bazelisk is also published to npm. Frontend developers may want to install it with npm install -g @bazel/bazelisk.
```

It would be awesome if bazelisk was also published on PyPi in a similar manner. PyPi offers the ability to distribute binaries - https://packaging.python.org/en/latest/specifications/binary-distribution-format/

Maybe something in [rules_python](https://rules-python.readthedocs.io/en/latest/pypi/index.html) could be helpful in making that happen?
