Actor movement simplified through Pivot removal. (gdquest-demos#64)

* Removed the use of a pivot.

This small change eliminates the use of a Pivot (Position2D) to move the character. The position is updated after the animation ends, which makes no difference since the update has already been done in the Grid.

* Updated Actor.tscn according to change in script.

This change reflects the changes in ./actor.gd

* Removed all instances of Pivot.

* Removed comments.
