display-plugin-updates shows downgrades

[krzyk]

I tried running 2.16.2 versions plugin to show me plugin updates, what it showed is mostly downgrades like:

[INFO] Require Maven 2.2.1 to use the following plugin updates:
[INFO]   maven-clean-plugin ................................. 3.3.1 -> 2.6.1
[INFO]   maven-compiler-plugin ............................... 3.11.0 -> 3.3

Now I noticed that it was because I didn't define minimum maven version.
