Merge #14720: rpc: Correctly name arguments

fa0815c300 rpc: Correctly name arguments (Jon Layton)

Pull request description:

  Consistently use the same name to describe arguments in the documentation and add a test that uses the name.

  By splitting it up, the changes are easier to potentially backport and also make review easier when we switch to `RPCHelpMan`.

  The tests should pass with or without the changes in `src`.

  Partly stolen from #14459 (More RPC help description fixes by ch4ot1c)
