Version check may recommend updating to an older version

[ashotland]

Version check server refresh latest version every hour.

If someone downloads the latest version before the server refresh dragonfly will prompt to upgrade because it only checks version inequality and doesn't consider the version number: https://github.com/dragonflydb/dragonfly/blob/a9d9b4935c43066da4c1e4e3a4eb51e43da10960/src/server/dfly_main.cc#L236

So maybe don't prompt if the resolved version is older than dragonfly's?
