Setting `TELEPORT_UNSTABLE_REJECT_OLD_CLIENTS=yes` on the Auth process now enforces that any clients connected are running a supported version. Clients connecting with an unsupported major version are terminated by Auth.

#38026 made rejecting client running unusupported major versions an opt-in behavior. Moving forward(v16 and beyond) this is now going to be an opt-out behavior(TELEPORT_UNSTABLE_ALLOW_OLD_CLIENTS=yes). In addition, a cluster alert is now being emitted once for the life of an Auth process if it rejects an unsupported client - with visibility limited to users with token:create permissions.
