Tracking Issue Substrate Module PBA3

• [x] Better diagrams, perhaps use mermaid

• [ ] revive tx-pool, find a spot for it. @JoshOrndorff
• [ ] based on the progress made in efforts like the polkadot-sdk mono-repo, https://github.com/paritytech/substrate/pull/14137 and such, I might revise and shrink "substrate-folder-structure".
• [x] General addressing of my post-lecture slides.
• [x] I want to revise the Merklized storage lecture, and frame it more around the concept of PoV. @JoshOrndorff would need to sync with you a bit, to see if/how Merkle proofs are covered in mod3.
• [x] revive frame-less template, and make it ready for auto-grading https://github.com/Polkadot-Blockchain-Academy/pba-content/issues/662, and aligned with mini_substrate
  • [ ] add proper nonce as a requirement to the assignment.

Other misc. tasks:

• [x] substrate crate docs, explaining some high level things and folder structure. https://github.com/paritytech/substrate/pull/14581
• [x] improve docs for sp_io https://github.com/paritytech/substrate/pull/14581
• [x] improve docs for sp_runtime::traits https://github.com/paritytech/substrate/pull/14583
• [ ] sp-keyring
• [ ] improve example/docs for ProofRecorder etc. An example of generating proof, even deletion proof would be good.
