Split Jupiter Origins, Add Origin Traits (Europa, New Gibson) (#22136)

Approved by lore (Schwann, Sammy).

changes:
- refactor: "Splits the Jupiter origin into three: ('Jupiter', 'Jupiter,
Callisto', 'Jupiter, Europa')."
- balance: "Characters with the Europa origin gain the Cold Resistance
and Light Sensitivity traits."
- balance: "Characters with the New Gibson origin gain the Cold
Resistance trait."
