fix(pypi): use local version specifiers for patched whl output (#2365)

Before this change the installation of the patched wheels using `uv` or
similar would break. This change fixes that by using local version
specifier, which is better than using a build tag when installing the
wheels.

Before the change:
```console
$ cd examples/bzlmod
$ bazel build @pip//requests:whl
$ uv pip install <path to requests wheel in the example>
error: The wheel filename "requests-2.25.1-patched-py2.py3-none-any.whl" has an invalid build tag: must start with a digit
```

After:
```
$ uv pip install <path to requests wheel in the example>

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.
