docs: Remove a Component instance from an Entity, by type.
  
          A Component instance can be removed by providing it's type.
          For example: world.delete_component(enemy_a, Velocity) will remove
          the Velocity instance from the Entity enemy_a.
  
          Raises a KeyError if either the given entity or Component type does
          not exist in the database.
          :param entity: The Entity to remove the Component from.
          :param component_type: The type of the Component to remove.
