Not sure if I should change the error message here or in a separate PR.
Might also want to add a note in the GDScript Reference for using min() max() to avoid short-circuiting.

Note that the documentation needs to be updated as well to mention bool, and probably change the wording of "numerical values", assuming this is approved

Now that you mentioned it, the Godot Doc implies that @GlobalScope.min() will work on Vector types, when in fact it only accepts int and float types:
https://docs.godotengine.org/en/4.6/classes/class_%40globalscope.html#class-globalscope-method-min

Edit: I updated the docs and code to also accept Vector types, so that it becomes consistent with Array.min(). The first commit is kept for comparison.
