d09fe3019e* [Server] Make resource subscribe/unsubscribe errors protocol-version-aware (SEP-2164) ReadResourceHandler already picked -32602 vs -32002 based on the negotiated revision; ResourceSubscribeHandler and ResourceUnsubscribeHandler still hard-coded the retired -32002 for every client. Bring them in line. * Remove unnecessary comments Co-authored-by: Christopher Hertel <mail@christopher-hertel.de>
