Update Multiple Resolutions demo for Godot 4.0

-A DynamicFont is also used to ensure font rendering remains crisp at high
-resolutions, thanks to Godot's built-in support for font oversampling. In other
-words, the engine will automatically re-rasterize fonts at different resolutions
-than the base window size when the window is resized (or when the window scale
-factor is changed).
+A DynamicFont with multichannel signed distance field (MSDF) rendering is also used.
+This allows for crisp font rendering at any resolution, without having to re-rasterize
+the font when the font size changes. This makes changing the various settings in this
+demo faster, especially when large font sizes are used as a result of the GUI scale factor
+setting being increased.
+
+Note that by default, Godot uses font oversampling for traditional rasterized
+DynamicFonts. This means MSDF fonts are *not* required to have crisp fonts at
+higher-than-default screen resolutions.

 ## Technical notes
 
 The demo works with the following project settings:
 
-- `2d` stretch mode (recommended for most non-pixel art games).
+- `canvas_items` stretch mode (formerly `2d`). Recommended for most non-pixel art games.
 - `expand` stretch aspect (allows support for multiple aspect ratios without
   distortion or black bars).
 - Using a base window size with a 1:1 aspect ratio (`648×648` in this demo).
