The `proto.Message.to_dict` function returns a `dict[str, Any]`, but its
return type annotation is incorrectly set to `Message`.

The `proto.Message.to_dict` function returns the result of calling
[`google.protobuf.json_format.MessageToDict()`](https://github.com/protocolbuffers/protobuf/blob/c58621b6ff2e6145ffb14c7e5a7af7648dfc0535/python/google/protobuf/json_format.py#L125-L162),
which returns `dict[str, Any]` as specified in the [protobuf typeshed
stubs](https://github.com/python/typeshed/blob/main/stubs/protobuf/google/protobuf/json_format.pyi#L23-L30).

Additionally, runtime introspection shows that the function returns a
`dict`.

The old `intersphinx_mapping` format has been removed; it must now map
identifiers to (target, inventory) tuples.

…tup.py (#502)

https://setuptools.pypa.io/en/latest/userguide/package_discovery.html
has a warning:

> Please have in mind that find_namespace: (setup.cfg),
> find_namespace_packages() (setup.py) and find (pyproject.toml)
> will scan all folders that you have in your project directory
> if you use a flat-layout.

That applies here.  Without this change, if you run:
'python3 setup.py bdist_wheel' then you may end up with
build/ in your wheel, and in some cases even
docs/ and testing/ .

The fix is to only include proto and proto.*.
