Fix cursor not showing pointer on task nodes in graph view (#63714)

[shashbha14]

Fixes a regression where the cursor no longer changed to a pointer when hovering over task nodes in the Graph view.
Changes

• TaskNode.tsx: Changed cursor="default" back to cursor="pointer" on the task node Flex wrapper
  Why ?
  The pointer cursor is an important UX signal that the task nodes are clickable. This had been set to default in a previous change.

Do you know what caused this regression? Because I am also unable to replicate this.

Closing.

That's not reproducible and most likely an AI generated fix that wasn't tested first. (targetting main 3.x, while original issue which isn't linked btw is for 2.11... #63714)

Similarly to the dozen of PR closed from this author closing this one.
