Add write-ups for tools section

[sacha-l]

The initial scaffolding just ports over some lean content about each tool. Now that we're treating each tool as a first class citizen, we need to provide proper write-ups for each one.

See: https://github.com/substrate-developer-hub/docs-sandbox/pull/16 for reference on a template to follow.

Currently working on:

• node-template CLI
• polkadot-launch
• substrate-archive

See working branch: https://github.com/substrate-developer-hub/docs-sandbox/tree/sl/tools-reference-section
