fix hatch build

without this change, running 'hatch build' in my environment (Ubuntu LTS
22.04) fails with:

  File

line 219, in default_file_selection_options
    raise ValueError(message)
ValueError: Unable to determine which files to ship inside the wheel
using the following heuristics:
https://hatch.pypa.io/latest/plugins/builder/wheel/#default-file-selection

At least one file selection option must be defined in the
`tool.hatch.build.targets.wheel` table, see:
https://hatch.pypa.io/latest/config/build/

As an example, if you intend to ship a directory named `foo` that
resides within a `src` directory located at the root of your project,
you can define the following:

[tool.hatch.build.targets.wheel]
packages = ["src/foo"]

with the change, the build succeeds
