[Interactive Graph Editor] Remove the use of graphKey for remounting

[nishasy]

Summary:

It turns out that the use of graphKey for remounting in
interactive-graph-editor.tsx is redundant, since this is also being
done by the useEffect in mafs-graph.tsx.

graphKey was also causing a warning to show up in the logs, possibly
from a remounting loop.

Here, graphKey is being removed altogether to stop the remounting issue.

Issue: none

Test plan:

Storybook

• http://localhost:6006/?path=/story/perseuseditor-editorpage--demo
• Add an interactive graph
• Open the browser console
• Move the graph in the "correct" preview (quickly! Don't hold for time before dragging)
• Confirm the warning doesn't appear
• Change properties of the graph (e.g. number of segments)
• Confirm that the preview changes correctly
• Repeat for every graph type
