Restore snap publishing on snapcraft

[bertrandfalguiere]

This is a placeholder for me to tackle this.
Snap publishing was removed because of #1547 : it was at the wrong place and it unpolitely interrupted testing.

@bertrandfalguiere - do you mind adding the appropriate labels to this issue when you get a chance? You can see details of the labeling system here: https://github.com/ipfs/community/blob/master/ISSUE_LABELS.md
Thanks!

[bertrandfalguiere]

I don't mind, but I think I don't have the right for it?

I think this could be
priority/P2
kind/enhancement or king/maintenance
need/community-input
dif/easy
effort/hours
status/in-progress
topic/package-manager

I can be assigned too, but I don't think I have the rights either.

@bertrandfalguiere, I'm sorry about the permissions! Thanks for that list. I added the labels and assigned you. 😊

The lowest friction route here seems to be adopting a snapcraft.yml file into this repo, and letting the snapstore build infra build out the snap files for us, and then promote new releases to the stable channel via the snapstore ui. I love full automation, but the periodic build failure from stale credentials will get annoying.

We are already publishing generic .tar.xz at well-known URLs:

• https://github.com/ipfs-shipyard/ipfs-desktop/releases/download/v0.12.1/ipfs-desktop-0.12.1-linux-x64.tar.xz

I believe we could go https://snapcraft.io/docs/pre-built-apps route and reuse prebuilt .tar.xz
That way Snap would be just thin wrapping on top of original artifact built by us.

@olizilla slayed the snap dragon for go-ipfs in ipfs/kubo#7250 (comment) 🛡🗡🐉!

Now it's a matter of time to be able to install ipfs-desktop from the default app store of Ubuntu, right?

[lidel]

@bertrandfalguiere yes, but it's a low priority for the team (limited bandwidth).

If anyone has time to create a PR to try approach from #1551 (comment) I'd be happy to test and review.
