Suggestion: auto-scroll Options sub-menu to top when open

[hsandt]

At small windowed resolution, the Options menu starts scrolled a little down (not sure why), and it also retains its last scroll value when closed and reopened.

We could auto-scroll it to the top each time it is open (if desirable, we could add a dev option flag for that).

Adding this code in options_menu_controller.gd > on_open:

$MarginContainer/ScrollContainer.scroll_vertical = 0.0

makes it work. To be cleaner, of course, we may want to store it in some member first:

@onready var scroll_container : ScrollContainer = $%ScrollContainer

and make ScrollContainer accessible as Unique Name so % works.
