Package wine-mono and wine-gecko into the container

[Tuupertunut]

Wine usually offers to download wine-mono and wine-gecko when creating a new wineprefix. However, as mentioned in the wiki https://wiki.winehq.org/Mono and https://wiki.winehq.org/Gecko, they can also be installed directly on the machine into /usr/share/wine/ so you don't need to download them for every new wineprefix. Could you add these packages into the container?

I thought about including them into the Conty's image, but unfortunately they don't compress well and take a lot of space. The image size with wine-gecko and wine-mono installed is ~250 MB larger than without them, so it's not worth it, in my opinion. It's better to let Wine download them on demand.

By the way, Wine doesn't download them for every new prefix, it downloads them once into XDG_CACHE_HOME (~/.cache/wine by default) and then uses the downloaded files for new prefixes.
