deps: rules_python 0.4.0 -> 0.22.0

Raise rules_python version to 0.22.0 so that py_proto_library is available.

The py_proto_library rule was introduced in 0.17.0, but there's been a variety
of fixes since then, so using a newer version is more advisable.

Note: A difference between 0.4.0 and 0.22.0 is that 0.4.0 calls `register_toolchains("@bazel_tools//tools/python:autodetecting_toolchain")`
to provide an extremely minimal, though incomplete, Python toolchain.
0.22.0 does not do that, and does not provide any Python toolchain by default.

Fixes #20315
