Merge bitcoin/bitcoin#23676: rpc: correct getnewaddress/getrawchangeaddress address_type helptext

5767208 correct rpc address_type helptext (brianddk)

Pull request description:

  RPC calls `getnewaddress`/`getrawchangeaddress` support the address_type of `bech32m` but it is omitted in the `RPCHelpMan` help text.

  The `createmultisig` and `addmultisigaddress` help text was not updated since `bech32m` is not yet supported in these.
