Autoloaded scripts should always inherit from Node. When you run a
project that tries to autoload a script which doesn’t inherit from Node,
then Godot gives an error.
Before this change, the error said “Script does not inherit a Node”.
That error message is a little bit misleading. If a class inherits a
Node, then one of its superclasses has a Node. If a class inherits
_from_ Node, then one of its superclasses is Node. This change corrects
that mistake.
Fixes#59884.
