Fix issue when publishing a new release to PyPI (#946)

Faced while running the following command in the CI (I was not able to
reproduce this locally):
```
Run python -m build
```

Resulted in the stacktrace:
```
    val = self.func(instance)
  File "/tmp/build-env-o83v4k67/lib/python3.10/site-packages/hatchling/builders/wheel.py", line 247, 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

The most likely cause of this is that there is no directory that matches the name of your project (astronomer_cosmos).

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"]

ERROR Backend subprocess exited when trying to invoke build_wheel
```

As seen in:

https://github.com/astronomer/astronomer-cosmos/actions/runs/8986616060/job/24683237685

I confirmed this worked between releasing Cosmos 1.4.0a3 and Cosmos
1.4.0a4.

(cherry picked from commit ebbc50c)
