Create tutorial or/and SDK for commiting scripts utxos into Head

[stanislav-az]

Why

Currently there is only information to get started with payment systems in documentation (and great tutorial btw). But it lacks in-depth tutorial for script related things in Hydra Heads. It is understandable, that we can use scripts inside heads because of ledger isomorphism. In other words, create new script utxos inside head and interact with these fresh utxos there. But, when it comes to committing utxos into head, it is not so trivial anymore, because script needs to be compatible with commit process: its utxo is consumed in commit phase.

What

Tutorial with code examples and a modification list to simple script (like forty-two one) on how to commit script utxo into Hydra Head. Also would be nice to grow a code base (SDK) for this script modifications in popular languages (plutus-tx, plutarch, aiken).

How

Add a tutorial to hydra.family doc site. And possibly links to example repositories or/and SDK.

We now have a "How-to" section where such piece of documentation would fit right-in: e.g. next to https://hydra.family/head-protocol/unstable/docs/how-to/commit-blueprint
