Mint-L themes are not provided / updated in Flathub

[billyswong]

This causes people who use Mint-L themes fail to get the theme applied to applications installed by Flatpak out of the box, as found in https://forums.linuxmint.com/viewtopic.php?t=400563

In https://github.com/orgs/flathub/repositories?q=org.gtk.Gtk3theme.Mint we get only the latest Mint-Y themes, and forgotten-to-rename "Mint-Y-darker" themes.

Edit: Mint-X themes are also missing there.

I would also like to use the Mint-L-Dark theme and Mint-L icons in Flatpak

In the meantime you can do

mkdir ~/.themes
mkdir ~/.icons
cp -r /usr/share/themes/Mint-L-Dark ~/.themes
cp -r /usr/share/icons/Mint-L ~/.icons
flatpak override --user --filesystem=xdg-data/themes:ro
flatpak override --user --filesystem=xdg-data/icons:ro

as a workaround
