Use the `keep` stretch aspect by default
Use the `keep` stretch aspect by default

This makes Godot avoid distortion when resizing the window to an aspect
ratio that doesn't match the project's base aspect ratio.

Since this setting has no effect when the stretch mode is `disabled`
(the default), this won't impact projects not using the `canvas_items`
or `viewport` stretch modes.
