Add inspect_ai eval logs support
The docs for this PR live [here](https://moon-ci-docs.huggingface.co/docs/datasets/pr_7899). All of your documentation changes will be reflected on that endpoint. The docs are available until 30 days after the last update. Very cool! 

Any reason not to directly use inspect for loading/converting from the binary format to JSON? https://inspect.aisi.org.uk/reference/inspect_ai.log.html#convert_eval_logs  The format is simple enough to not have to rely on an additional dependency :)
Support for .eval log files from inspect_ai

They are actually ZIP files according to the source code at https://github.com/UKGovernmentBEIS/inspect_ai/blob/main/src/inspect_ai/log/_log.py

Unfortunately their format can't be converted to Parquet, so I had to JSON-encode all the nested values

```python
ds = load_dataset("dvilasuero/kimi-bfcl")
```

this will enable the Viewer for datasets like https://huggingface.co/datasets/dvilasuero/kimi-bfcl
