[Keith-CY]

1. Update the RFC number;
2. Adjust the order of the example to match sections below;
3. Rename chainId as reference that used in https://github.com/ChainAgnostic/CAIPs/blob/main/CAIPs/caip-2.md
4. Rename chainId as chain_id that used in https://github.com/ChainAgnostic/CAIPs/blob/main/CAIPs/caip-10.md
5. Fix the reference to a script from code hash to code hash + hash type

I also found some missing details

1. the method to connect the wallet is missing
2. Types Address and Transaction are mentioned but not defined in the doc
3. In the section ckb_getAddresses, type: derived | all is mentioned but not explained. It's the concept specifically in this RFC and is not explained elsewhere.
4. changeType: add | consume is mentioned in the addressesChanged section but is not explained

There is no need to define method connect in namespaces.

Where should I check the information about

  sessionProperties: {
    lockCodeHashes: "secp256k1,acp",
  },

to set required script_base on connecting to the wallet?
