Scene recognizes @tool only on open

[GniLudio]

Godot version: v4.3.stable.official [77dcf97d8]

Issue description: When adding (or removing) the @tool-tag from a script, opened scenes don't detect the change automatically. Only when closing and reopening a scene, the scene correctly detects the added/removed @tool.

Documentation Page: Running code in the editor

Steps:

1. Create a scene
2. Add the script to the scene
   • Add @tool to the start of the script
   • Add print("Hello") to the _process function
3. Switch back to the scene -> no 'Hello' appears in the console
4. Close and reopen the scene -> 'Hello' appears in the console

func _process(delta: float) -> void:
    print("Hello")
