Prop 24: Enabling Set Withdraw Address Transaction Feature

This proposal advocates for the authorization of the 'set withdraw address' transaction. The plan necessitates modifying the chains parameter to set WithdrawAddrEnabled as True. This adjustment allows validator to get their rewards on another wallet (specified by the set-withdrawal-addr transaction) instead of the wallet which created the validator. If no withdrawal address is set, rewards will go on the wallet that created the validator. Presently, this functionality is non-operational on FetchAI. Enabling it would significantly streamline and transform validator's regular operations. Link to the governance discussion on FetchAI's Github : https://github.com/fetchai/FIPs/discussions/23
