Reorganize repository into quick starts and deep dives

[alimaredia]

Examples in the repository now fall into two
categories: deep dives and quick starts.

Update README.md to reflect new repo structure

Thanks for putting this together @alimaredia and initiating this important reorganization.

I've reviewed the proposed changes, and I see strong alignment with the vision we've been discussing for the repo's IA and its goals of being an informative, useful resource for AI model customization. I particularly like the inclusion of model_customization_examples/, e2e_examples/, and community_examples/, as these are key categories for our content.

Building on this, I propose a few refinements to streamline the top-level Information Architecture and enhance user experience, especially for beginners:

• Streamlined Top-Level: My suggestion is to remove the official_examples/ wrapper. If all notebooks we publish are vetted, this wrapper becomes redundant. I propose elevating the core categories directly to the root.
• Explicit Onboarding: Introduce a 00_getting-started/ top-level directory. It establishes a clear, numbered entry point for a progressive learning path.
• Refined Community: Keep 03_community-examples/, potentially with vetted/ and unvetted/ sub-sections.

This refined structure would look something like:

README.md
00_getting-started/
01_model-customization/
02_end-to-end-flows/
03_community-examples/

I've created a branch named repo-restructure which I will show this structure.

I'd be happy to discuss these refinements and walk you through the structure in my branch. Let me know what you think!

@alimaredia here is my branch

Is the latest work in the e2e notebook here? Printing randomly selected chunks and Q&A customization are not there. Are those intended to be deep dives? That would make sense to me.
