Ambiguous version message

[jalanb]

Describe the bug

When running vermin on my code I see:

 $ vermin pysyte/
Minimum required versions: 3.9
Incompatible versions:     2

The last line is ambiguous and left me wondering: "which two versions??"

To Reproduce

 $ vermin pysyte/

Expected behavior

 $ vermin pysyte/
Minimum required versions: 3.9
Incompatible versions:     2.x

removes the ambiguity, and makes it obvious that "2" means the version number
