Rename the nodes 'Length' -> 'Magnitude', 'Flatten Path' -> 'Combine Paths', 'Vec2 Value' -> 'Combine Vec2', and add a new 'Vec2 Value' node (#4349)

* Rename the node 'Length' -> 'Magnitude'

* Rename the node 'Flatten Path' -> 'Combine Paths'

* Replace the node 'Vec2 Value' with 'Combine Vec2' and add a new 'Vec2 Value' that's actually a vec2

* Update demo artwork
