Limit nodes opened by default in the JSON Tree component (#11002)

- Add a parameter to choose which nodes to open by default
- On the Admin Panel, open all nodes by default
- On the Workflow Run step output, open only the two first depths
- On the Workflow Run step input, open only the previous step first
depth
- Display `[empty string]` when a node is an empty string
- Now, display `null` instead of `[null]`
