Merge #14448: doc: Clarify rpcwallet flag url change

0c69ff6 clarify rpcwallet flag url change (Jordan Baczuk)

Pull request description:

  This adds clarification to the bitcoin-cli -rpcwallet flag in the help command. This will benefit users who want to utilize this feature without the cli, for example curl. It isn't readily apparent that this changes the url used in the RPC call.
