chore(docs): replace llama3.1 with qwen2.5 on ollama docs

[henchaves]

Description

Sometimes llama3.1 model doesn't generate JSON responses in a proper format. After doing some manual tests, we have seen that qwen2.5 performs better on this task. Therefore, this PR updates the Ollama docs to showcase qwen2.5 as model example instead of llama3.1.
