VSCode Extension - Long Resource Names + IntelliSense = Hard to navigate sometimes

Most of the IntelliSense suggestions that I've been using can usually be navigated with ease. For example `Microsoft.Web/` is relatively small and contains several child resources:

However with something as long as `Microsoft.OperationalInsights/workspaces` its hard to figure out what each entry actually is. Even the right portion of the popup is cut off.

## Possible Solution
### More descriptive context
Given the right portion of the popup renders `Provider / Resource / Child Resource / Child Resource @ Version` maybe we can parse it into smaller chunks:

> **Type**: `Microsoft.OperationalInsights/workspaces/linkedStorageAccounts`
> **Provider**: `Microsoft.OperationalInsights`
> **Resource**: `workspaces/linkedStorageAccounts`

or

> **Provider**: `Microsoft.OperationalInsights`
> **Type**: `workspaces/linkedStorageAccounts`

**UPDATE**
After researching I learned that VSCode does have the ability to resize these windows using the mouse. I still think that maybe rendering more information in the VSCode plugin could be beneficial?

Start by reproducing the long-resource-name IntelliSense popup in the VS Code extension, especially for Microsoft.OperationalInsights/workspaces/linkedStorageAccounts. Review the proposed provider and resource/type presentations, then define a concise rendering that keeps the full context visible and verify it against both short and long resource names.
