Remove `room_version` param from `check_auth_rules_for_event`

Instead, use the `room_version` property of the event we're checking.

The `room_version` was originally added as a parameter somewhere around #4482,
but really it's been redundant since #6875 added a `room_version` field to `EventBase`.
