Require can be changed to custom revert

[allwin199]

Description

require can be refactored to customRevert

chainlink/contracts/src/v0.8/KeepersVRFConsumer.sol

Lines 85 to 93 in 7b06aa1

	function fulfillRandomWords(uint256 requestId, uint256[] memory randomWords) internal override {
	// Check that the request exists. If not, revert.
	RequestRecord memory record = s_requests[requestId];
	require(record.requestId == requestId, "request ID not found in map");
	// Update the randomness in the record, and increment the response counter.
	s_requests[requestId].randomness = randomWords[0];
	s_vrfResponseCounter++;
	}

In the below code, custom revert is used.

chainlink/contracts/src/v0.8/PermissionedForwardProxy.sol

Lines 29 to 32 in 7b06aa1

	function forward(address target, bytes calldata handler) external {
	if (s_forwardPermissionList[msg.sender] != target) {
	revert PermissionNotSet();
	}
