feat: Add Milkman Tutorial

Problem

We have people trying to create milkman orders not knowing how to create the correct calldata, how to simulate their deployment beforehand and how to debug if their order isn't getting matched

Suggested solution

A clear and concise tutorial showing all steps (including how to run your own milkman bot)

Alternatives considered

Completely ditch milkman in favor of programmatic orders, although given its success and everything else going on at the moment it's probably worthwhile documenting.

Additional context

@cmagan may have some scattered bits and pieces of such a tutorial in notion/hackmd somewhere. There is also this debugging tutorial in Notion

Acceptance criteria

Next time we have a tg support request, we can direct them to this tutorial and they can unblock themselves.

Start by gathering the scattered tutorial material mentioned for @cmagan and review the linked Notion debugging tutorial. Organize guidance for creating Milkman calldata, simulating deployment, diagnosing unmatched orders, and running a Milkman bot. Done means support requests can be answered by linking to the tutorial and users can unblock themselves.
