[Bug][Move] Shed Tail now rounds incurred damage up, not down (#5219)

* Shed Tail rounds incurred damage up

* Altered Substitute/Shed Tail success condition to account for rounding up

* Altered the test to match correct functionality

* Update src/data/move.ts

Removed default value in constructor due to it having become redundant
