This PR contains:

• [ ] a new test-case for the benchmark
  • [ ] I hereby confirm that NO LLM-based technology (such as github copilot) was used while writing this benchmark
• [ ] new dependencies in requirements.txt
  • [ ] The environment.yml file was updated using the command conda env export > environment.yml
• [x] new generator-functions allowing to sample from other LLMs
• [x] new samples (sample_....jsonl files)
• [x] new benchmarking results (..._results.jsonl files)
• [x] documentation update
• [ ] bug fixes

Short description:

• This adds a new LLM to the benchmark: claude-3.5-sonnet

How do you think will this influence the benchmark results?

• claude-3.5-sonnet is the new leading model in our benchmark
• results from other LLMs are not changed

Why do you think it makes sense to merge this PR?

• There was a hype around this new model in social media, with claims it outperforms gpt-4o in many benchmarks. We can confirm this claim. Hence, we should include it in our list.

Before merging this, we need to update thet paper text though,
