Merge #14726: Use RPCHelpMan for all RPCs

fa5e0452e875a7ca6bf6fe61fdd652d341eece40 rpc: Documentation fixups (MarcoFalke)
fa91e8eda541acdb78ca481b74605639f319c108 Use RPCHelpMan for all RPCs (MarcoFalke)
fa520e72f7b5964cea1ade666e71212914556cf3 lint: Must use RPCHelpMan to generate the RPC docs (MarcoFalke)

Pull request description:

  The resulting documentation should not change unless the type in the oneline-summary was previously incorrect. (E.g. string vs bool)
