rpc_methods did not include rpc_methods

rpc_methods should include itself in the response

Hey, it's been like that for a very long time IIRC.

The format is:
{"jsonrpc":"2.0","result":{"methods":[<methods here>]}

Are you saying that you want it in the list methods such as [<methods>, "rpc_methods"]?

[xlc]

Yes.

We implemented a nodejs server that can forwards RPC calls to Substrate RPC node. It uses rpc_methods to determine the available rpc methods. And it failed to forward rpc_methods because that's not included from the response from rpc_methods.
