fix(gazelle): Do not build proto targets with default Gazelle (#3216)

Fixes #3209.

Revert the change to `//:gazelle_binary` so that it once again only
generates python code. We then create a new, private target
`//:_gazelle_binary_with_proto` that gets used by tests.

Update docs accordingly.

Longer term, I'd like to adjust the `test.yaml` file to include a
section:

```yaml
config:
  gazelle_binary: _gazelle_binary_with_proto
```

So that test cases that need to generate `(py_)proto_library` targets
can use the multi-lang Gazelle binary and that tests that do _not_ need
to generate proto targets can use the single-lang Gazelle binary.

However, there were some minor roadblocks in doing so and thus I'm doing
this quick-to-implement method instead.

Python Rules for Bazel

Build status

Overview

This repository is the home of the core Python rules -- py_library, py_binary, py_test, py_proto_library, and related symbols that provide the basis for Python support in Bazel. It also contains package installation rules for integrating with PyPI and other indices.

Documentation for rules_python is at https://rules-python.readthedocs.io and in the Bazel Build Encyclopedia.

Examples live in the examples directory.

The core rules are stable. Their implementation is subject to Bazel's backward compatibility policy. This repository aims to follow semantic versioning.

The Bazel community maintains this repository. Neither Google nor the Bazel team provides support for the code. However, this repository is part of the test suite used to vet new Bazel releases. See How to contribute page for information on our development workflow.
