Add Date Executed values for executed proposals

[jmrossy]

Through a query for proposal execution events to the governance contract, we can get the list of executed proposals (see below): https://api.celoscan.io/api?module=logs&action=getLogs&fromBlock=0&toBlock=latest&address=0xD533Ca259b330c7A88f74E000a3FaEa2d63B7972&topic0=0x712ae1383f79ac853f8d882153778e0260ef8f03b504e2866e0593e04d2b291f

To add this useful info to the CGPs, someone will need to go through them, finding the CGP these on-chain IDs map too (see governance-proposal-id field), and then add these dates in the date-executed field formatted like 2024-01-12.
