EPIC: Usage Documentation

[evan-forbes]

We are already trying to have some form of accurate specs in #650, which will help a lot in terms of documentation, but we still need a lot of documentation relating to usage of code related to core/app.

• Document gas usage by MsgPayForBlobs #397 (could also have a copy in the specs)
• Explore using goreadme for package-specific README #870
• Update blob module docuementation #1113
• Document token filter middleware #1267
• Document all exported functions #1321

QGB related

• Document QGB verify command usage #1254
• QGB Inclusion proofs #956
• Document the orchestrator and relayer usage orchestrator-relayer#2
• Update the openapi.yml to contain inclusion proofs RPC celestia-core#925

I would also add here: documenting of IBC's token filter middleware

we have yet to complete #1321, however the rest of the points have been addressed and this epic is a bit stale.

If we want to prioritize other efforts for usage documentation we should create a new epic with updated issues
