n0252-0254 Sceptile Line Hacked Changes

Part of the Cobblemon Hacked Changes series, I am now separating my one mod into separate Datapacks. This datapack targets the sceptile evolutionary line from generation three. This datapack changes the gecko pokemon to be grass/dragon type, changes unburden to its secondary ability and sharpness to its hidden ability, changes its stats (notably increasing its attack power at the cost of special attack), and makes changes to its movepool.
