The bulk update request #9761 is pending approval.

create alias saberstaff (48) -> double-bladed_lightsaber (0)
create alias double_bladed_lightsaber (4) -> double-bladed_lightsaber (0)
create implication double-bladed_lightsaber (0) -> lightsaber (1070)
create implication crossguard_lightsaber (19) -> lightsaber (1070)
create implication lightwhip (1) -> lightsaber (1070)

Reason: Some lightsaber variants as well. I went with double-bladed_lightsaber bc that's the name Wookieepedia uses: https://starwars.fandom.com/wiki/Double-bladed_lightsaber/Legends
