Identity Graph Screenshots Represent a Poor and Discouraged Implementation Pattern

Issue in ./help/identity-service/features/identity-graph-viewer.md

Ten of the screenshots on this page show an identity graph with email connected to email. In a real-world implementation, you'd never want to send in the kind of data that would generate a graph like that. And with Graph Linking Rules now live, any hit that would send in that kind of graph would likely be rejected. If we saw that kind of graph in a customer implementation, we'd ask them to fix it.

Please update the screenshots and any corresponding text such that two identical namespaces are never connected to each other.

Open help/identity-service/features/identity-graph-viewer.md and review the ten screenshots showing email connected to email, along with their corresponding text. Update the screenshots and text so no two identical namespaces are connected, then verify the page consistently reflects the requested implementation pattern.
