Packaging: Makes sure all POMs contain a description

Adds an explicit description the RPM package so it doesn't inherit the description from the POM.

Closes #12550

Also, modified descriptions for deb and rpm packages to be the same and to reference the documentation rather than listing features that are out of date.
