documentation: GUI Widget Gallery example seems to have a few bugs

[simodoe]

I'm brand new to Arcade and checking out the example code.

When I ran GUI Widget Gallery, a few things didn't work.

• in the Constructs tab, button-row buttons don't seem to do anything. "default style" will bold text if it's not already bold, but that's it. Neither "red style" nor "blue style" cause any change.
• In the Text tab, there is a large textarea with an arrow indicating you can scroll to view more context. But I could not get that text to display by clicking the arrow, rolling my mousewheel, or pressing down arrow keys. I even tried resizing the window and it's nonresizable.

Thank you for the feedback.

• The button-row actually does nothing, we will iterate on that.
• The text area should be scrollable using the mouse wheel. did you try both directions? Please let us know which os you are using.

@simodoe What OS are you running on? Did you try to scroll in both directions?
