[Docs] Reference Data Grid Server Guide in the Helm chart docs

Provide more configuration examples for customers who use Helm Charts. 

Solution: We have existing yaml examples in the Data Grid Server guide that we can reference in the DG Helm Chart documentation

Outcome: The Helm documentation includes references to other DG guides (server, security, CLI, configuration guide). No need to take any action.

When I was checking the docs I found a broken link.
