Fix checking the current Tarantool version for minimum requirements

[valery1707]

The actual version will assume that version "3.2" is less than version "2.3" because 3 >= 2 && 2 >= 3 will computed as false.

I haven't forgotten about:

• Tests
• Changelog
  (seems that internal changes do not need to be reflected in Changelog)
• Documentation
• Commit messages comply with the guideline
• Cleanup the code for review. See checklist

Related issues: none

LGTM. I don't see any problems here
