Relate the CLI getting started guide to the contract being executed

[iAmMichaelConnor]

Some user feedback:
"
It would be nice to see a code snippet of the noir script used in the example. I think it would be a great opportunity to explain the primitives / quirks of noir so I can fully understand what is happening when I am transferring crypto from Alice to Bob.
The sandbox is somewhat underwhelming once i got it working. the noir script code snippet would fix this! I wanna know what is happening.
"

In dev_docs/getting_started/cli, provide code snippets of the relevant functions that will be executed. Provide links to elsewhere in the docs for explanations about the syntax. Also provide a link to the section of the docs which explains how to write a noir contract.

To reduce clutter, we should collapse the noir contract code snippets into an expandable section, using https://docusaurus.io/docs/markdown-features#details .

@critesjosh I'm going through old issues that I opened, that might have been missed. Just pinging you if this is still relevant? If not, please feel free to close it :)
