Installation fails from PyPI: missing __version__ with dynamic version setting

[AntonyCM94]

Hi, Whisper Team
While trying to install the latest version from PyPI ('v20240930'), I encountered the following error:

``` toml
[tool.setuptools.dynamic]
version = { attr = "whisper.version.__version__"}

However, the file whisper/version.py does not exist, so pip fails to retrieve the version during build time.

Suggested fix:

1. Either define the version explicitly in [project]:
   version: "20240930"
2. Or create whisper/version.py with:
   __version__ ="20240930"``

I'm experiencing the same. I notice that when I attempt to install via pip with Python 3.12.8, everything works as expected; I only run into this when I install on a Python 3.13 variant.

With 3.13, installation directly from the repo works:

pip install git+https://github.com/openai/whisper.git@v20240930

It also works for me when I run
pip install git+https://github.com/openai/whisper.git@v20240930
