Improve versions check

[ivan-hc]

Continuation of #2300

The table in the foreground is the new one, you can see some more complete versions

@ivan-hc zsync2 cannot be rolled back anymore after this update, the ./test-am-rollback caught it. It just says ERROR: No valid links found, sorry!

The version it is showing seems to be incorrect:

- APPNAME | VERSION   | TYPE        | SIZE
◆ zsync2  | fc62ae7 ✓ | appimage    | 11.92 MiB

Before this, it would show v93, previous version was v92.

@vishnu350 what are you talking about?

Sure the version is different in the URL, but the latest commit is a value more reliable than a version.

In Alpine Linux:
◆ zsync2 | fc62ae7 ✓ | appimage | 11.92 MiB

In Debian Jessie:
◆ zsync2 | 2.0 ✓ | appimage | 11.92 MiB

In Debian latest:
◆ zsync2 | 93 ✓ | appimage | 11.92 MiB

Only Alpine Linux has the rollback problem, other distros are OK.

Maybe ignore this for now, I will try to debug it later.

In Debian Testing I have the same result as Alpine

This should fix the issue @vishnu350 baa67d7
