Feature request: Use dark text on a bright background

[David Hedlund]

* The default background color in Ubuntu MATE 22.04 is white.
* The default background color in Ubuntu 22.04, and 23.04, is tyrian purple-ish (very dark). A dark background will cause eye-straining on day time use.

This will turn off the default theme and use a light-purple background instead:

profile_key=$(gsettings get org.gnome.Terminal.ProfilesList default | sed -e "s/'//g" | tr -d "\n")
gsettings set org.gnome.Terminal.Legacy.Profile:/org/gnome/terminal/legacy/profiles:/:$profile_key/ use-theme-colors false
gsettings set org.gnome.Terminal.Legacy.Profile:/org/gnome/terminal/legacy/profiles:/:$profile_key/ background-color "'rgb(255,224,255)'"
