Update Documentation

[lapp0]

Rendered: https://lapp0.github.io/outlines/quickstart/

Changes

• Create model.md documentation with feature matrix
• Update quickstart.md so its more concise, and links to relevant reference/generation/index.md and reference/models/index.md documentation pages. Moves most structured generation examples to reference/generation/index.md
• Include structured_generation_explanation.md which details automata construction and logits processing.
• Use phi-3-mini instead of mistral in all pages except external libraries cookbooks because it doesn't require an access token and is a more performant model for its size.
• Add Remi's AI Engineer World’s Fair Presentation

Fixes

• Fixes Feature Matrix #675
• Fixes Add documentation for models #477
• Fixes Json schema generation not outputting full schema. #1007

Thanks for the doc update! Two comments:

• We can remove Mistral-7B from the README as well. I also saw it in a couple of places in the rendered doc.
• For the talk we'll have to do with the current video for now.

Updated docs

• added Remi's AI Engineer World’s Fair Presentation
• removed mistralai/Mistral-7B-* everywhere
• kept documentation which uses quants, e.g. TheBloke/Mistral-7B-Instruct-v0.2-GPTQ
• kept external library guides in cookbook using mistral, e.g.

docs/cookbook/simtom.md:MODEL_NAME = "mistral-community/Mistral-7B-Instruct-v0.3"

We need to fix the merge conflict and then it should be ready to merge.
