Streamlining GangKarmaRequirement constant

As suggested by phyzical :

The GangKarmaRequirement const was declared locally in the PlayerObjectGangMethod.ts file.

It's now part of the GangConstants object in the gang/data/constant.ts file.

Allowing it to be referenced in the FactionRoot.tsx tooltip.
