Add information on additional formulas for Dice scale values

[arbron]

Currently dice scale values list and provide a copy button for the whole formula (@scale.fighter.superiorityDice) but not to the new formulas needed to access portions (@scale.fighter.superiorityDice.number, @scale.fighter.superiorityDice.faces, and @scale.fighter.superiorityDice.die) making those formulas difficult to discover.
