Saves having this defined in 20+ places. If we ever make any changes to
shear, it's 100% going to need to be applied to every usage (there will
never be a case of multiple different shears in the game).
Also fixes a mismatching definition in `ShearedNub`.
Going simple with a bool instead of making `TooltipText` init-able, as the current cases will just init `string.Empty`. And not sure if we want custom tooltip text in the future.
