fix(bzlmod): allow users to specify extra targets to be added to hub repos (#2369)

Before this change, it was impossible for users to use the targets
created with `additive_build_content` whl annotation unless they relied
on the implementation detail of the naming of the spoke repositories and
had `use_repo` statements in their `MODULE.bazel` files importing the
spoke repos.

With #2325 in the works, users will have to change their `use_repo`
statements, which is going to be disruptive. In order to offer them an
alternative for not relying on the names of the spokes, there has to be
a way to expose the extra targets created and this PR implements a
method. Incidentally, the same would have happened if we wanted to
stabilize the #260 work and mark `experimental_index_url` as
non-experimental anymore.

I was hoping we could autodetect them by parsing the build content
ourselves in the `pip` extension, but it turned out to be extremely
tricky and I figured that it was better to have an API rather than not
have it.

Whilst at it, also relax the naming requirements for the
`whl_modifications` attribute.

Fixes #2187

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.
