create alias skybridge -> skyway

BUR #2357 has been approved by @evazion.

create alias skyway -> skybridge

Reason: Neither is very populated, but an alias might still be appropriate because the one we don't keep would probably end up repopulated otherwise.

EDIT: The bulk update request #2357 (forum #164043) has been approved by @evazion.

Skyway is unfortunately ambiguous and can refer to three things: (1) airline routes, (2) elevated roads (highways), (3) elevated corridor/bridge connecting buildings (or similar connecting within a building across an atrium). I think skybridge would be better as it is not as ambiguous and seems more obvious at a glance as to what it might be.

Reversed the request.
