Inventory of PBA content for use in the Substrate Docs and Polkadot Wiki

[nuke-web3]

https://github.com/Polkadot-Blockchain-Academy/pba-content will inevitably have content that is crafted for an in-person experience that could be repackaged in async written form. @Polkadot-Blockchain-Academy/content-creators let's use this thread to identify what we see as good candidates to be used as basis to make new/updated https://docs.substrate.io/ and https://wiki.polkadot.network/ content.

I would also invite @lisa-parity, @alfarok, and @DrW3RK as leads for the docs and wiki to identify topics and make suggestions around how we all can help you making that happen.
