Wrong RPC path (w3f#4247)

* Wrong RPC path 

I think the path should be "consts.staking.maxNominatorRewardedPerValidator" not query. Kusama is currently 512 but because of the wrong path the wiki shows the wrong default of 256. Would default "0" not be better so errors show up quicker?

 slashing! Every active nominator of the validator committing slashable offence will be slashed.
