Description of problem:

The dynamic demo plugin locales is missing a correct plural string. The  dynamic demo plugin doesn't make use of the script console uses to transform plural strings, so we need to update the plural string manually 

This would help with the further validation of i18n dependencies update changes, and also the investigation of [Dynamic plugin translation support for plurals broken](https://issues.redhat.com/browse/OCPBUGS-11285) bug

Steps to Reproduce:

1. Deploy dynamic demo plugin on a cluster
2. Goto Overview page
3.
