Introducing an internal bus CommitInputs, the external inputs of the top level circuits have not been updated, therefore, no solidity or circuit test files needed to be updated.

Also

• fixed spelling warnings in VS code
• fixed some spelling errors

Added approval. would be good to add explanation as to why the KYC solidity verification parameters have changed.

[Chengxuan]

I can't tell why the KYC solidity verification parameters have changed while the sol verifier of all the other anon_enc_nullifier prefixed circuits remain unchanged. The change across all 3 anon_enc_nullifier prefixed circuits is identical in this PR.
