Make the node graph use Table<GradientStops> instead of GradientStops (#3837)

* Switch from GradientStops to Table<GradientStops> in all nodes

* Remove TaggedValue::ColorNotInTable

* Fix bug

Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com>

* Add migrations

* Fix default gradient on empty table

* Update demo artwork
