Mention snap in install instructions
|Reported by:||popey||Owned by:||sev-|
There is now (and has been for nearly a year) a snap of ScummVM available in the snap store. There's been some hundreds of downloads of it from there with no promotion. It would be awesome to get this listed on the ScummVM download page. 
Having a snap makes it super easy for users of snap-enabled systems to install ScummVM, and get automatic updates when the app in the store is updated.
Some suggested text for the download page, with perhaps the words 'snap-enabled' linking to https://snapcraft.io/docs/core/install:-
"On snap-enabled systems, install ScummVM with:- snap install scummvm".
The snap was uploaded by an enthusiastic community member, and if wanted the ownership of that package in the store could be handed over to the ScummVM core team for updates.
