lab3 needs more work to run

[afrancoc2000]

When I tried to run the lab 3 as said in the guide, I encountered an issue with the documents. They came with the vectors and that made it impossible to run in the queries to the LLM.

I had to:

1. Change documents input type to list.
2. Change validate_input block adding a validate_list method without the strip string.
3. Change every prompt block that included a {{FullBody}} line in the jinga2 file like this:

{% for document in documents %}
{{ document.text }}

{% endfor %}

After running these steps, I was finally able to do the evaluation of the results.

Hi Ana, thanks for the feedback. I pushed some updates on labs 2 and 3 related to the indexing approach for the RAG part that will solve this issue, let me know in case you face additional issues. #8
