Update setup.py to accommodate Python3.13.0

*Changes made*

- Update `setup.py` to pass in a local dictionary to `exec` to capture
  the `locals()` in `_version.py` for package version reporting.

*Motivation*

- `Python3.13.0` enforces stricter safety standards on `locals()` with
  PEP 667 (see [here](https://github.com/python/cpython/issues/118888#issuecomment-2104944287))

- This causes the following error upon attempting to install with
  `python3.13 -m pip install openai-whisper`:

```bash

*EXTRA NOTES*

- This does not enable `openai-whisper` to be pip installed with
  `Python3.13`, due to a dependency on the `numba` library. This issue
  and missing dependency can be tracked [here](https://github.com/numba/numba/issues/9413)
