Problem

The WithdrawDelegatorReward method in the Cosmos SDK's x/distribution module is currently exposed in the cosmos/evm distribution precompile as WithdrawDelegatorRewards (note the added "s").

This naming inconsistency may cause confusion when comparing the SDK and EVM interfaces.

Closing criteria

• Rename the method to WithdrawDelegatorReward in the precompile for naming consistency with the Cosmos SDK.
