Migrate from gz compression to zstd for backups

I’d be curious to know the average weight ratio between compressible and already compressed data in a Discourse backup[1], and how much data (in %) would be saved using zstd.

It’s not the same feature request, but it’s also about backup compression so I’m crossposting this:

I wouldn’t be surprised if the percentage was about the same on all my Discourse forums.
