fix(pypi): include RECORD file in installed wheel targets

Currently, `importlib.metadata.files()` returns `None` for packages installed via `rules_python`'s wheel rules. This happens because the `RECORD` file in the `.dist-info` directory is explicitly excluded from the `data` attribute of the generated `py_library` targets.

To fix this, remove `**/*.dist-info/RECORD` from the `_data_exclude` list in `whl_library_targets.bzl`. This ensures that the `RECORD` file is preserved in the runfiles and available at runtime, enabling `importlib.metadata.files()` to correctly list the files in the package.
