Add practical examples to fromager documentation

[LalatenduMohanty]

We have https://github.com/LalatenduMohanty/learning-fromager which has some pratical examples which can help new users to quickly learn fromager. But we should take the existing documentation from https://github.com/LalatenduMohanty/learning-fromager and add it to the fromager official documentation. There is no reason to have separate documentation in another git repository.

I'd like to work on this. I want to know if there is a JIRA ticket for this?

I'm thinking we could introduce a new learning-fromager/ directory in the main fromager repo with the following structure:
fromager/
|── learning-fromager/
| |── Fromager-learning-guide.md (renamed from README.md)
| |── examples/ (all example directories from your repo)
│ |── setup.sh
│ |── cleanup.sh

For discoverability, I'm thinking we should link to the learning guide in the main README. Would you prefer:
Option 1: Add under "Additional docs" section:
Practical Learning Guide - Hands-on examples and tutorials
Option 2: Add a new "Getting Started" section:

Getting Started

Let me know if this works or if you were thinking of a different approach

We just need to copy the content from https://github.com/LalatenduMohanty/learning-fromager/blob/main/README.md to a new page under getting started https://fromager.readthedocs.io/en/latest/getting-started.html , please ignore the shell scripts. those are the extra details which is not required IMO.
