Decide if WallpaperSelectorViewController's instructionLabel should be body or caption1 text size

Related to https://mozilla-hub.atlassian.net/browse/FXIOS-9382

The subtitle for the wallpaper selector was formerly a size 12 font. We want to standardize our app fonts to use common FXFontStyles.

• Should this font be mapped to the body font, which is size 17? (Seems more semantically accurate)
• Or, should this font be mapped to a caption1 to preserve the current UI appearance?

Current wallpaper overlay UI:

Possible change the bottom wallpaper overlay label to size 17 body font:

Hi Crystal Wong, this is a UI related question we have for you. We’re curious if you think the font should stay the same or if you think it makes sense to update the label to a body size font as we standardize the app fonts. Thanks!
