Geo - Versions Error Fix

What does this MR do?

Closes #197986 (closed)

In Geo there are two types of Nodes. A singular Primary node and an infinite amount of Secondary nodes. We check to make sure all the secondary nodes match the primary nodes version and show an error if there is a mismatch.

This change adds a logic check to ensure we don't show that error on the primary node itself, since it doesn't make much since to say "The primary node version doesn't match the primary node version".
