Wrong ffmpeg download -> 404

### Classifications

- [ ] Running `python ./jellybench_py/hwi.py` manually (within the Poetry shell) works and produces correct results.
- [x] This happens on a Virtual Hardware (VM, WSL, ...)
- [ ] The issue occurs during the benchmark section of the script (after `Starting Benchmark...`).
- [x] A server issue or faulty server response is causing the problem.
- [ ] jellybench was run in `--debug` mode (recommended for issue reports).
- [x] I am using the latest version (branch `develop`) of jellybench. I understand older versions are not supported.

### Description

jellybench queries an API to select an ffmpeg version but the API returns an ffmpeg artifact which no longer exists, producing this output:

```
uv run jellybench --debug
