Motivation & Context

The Purview package guide illustrates PurviewPolicyMiddleware(settings=settings), but the constructor requires a credential as well. It also describes PurviewSettings as Pydantic settings although the current type is a TypedDict.

Description & Review Guide

• What are the major changes? Pass DefaultAzureCredential() to the illustrated constructor and describe the settings type accurately. The existing ellipses remain application-specific placeholders.
• What is the impact of these changes? The guide matches the existing API; runtime code is unchanged. Windows local construction controls used current source. No token acquisition, middleware/policy execution, HTTP request, cloud/model, package build, full suite, or full sample execution was performed.
• What do you want reviewers to focus on? The required credential argument and the settings type match the implementation and existing README pattern.

N/A - trivial change: correct an existing documentation example to supply an already-required parameter and fix its settings-type description. No API or runtime change.

The guide now matches the existing Purview API: PurviewPolicyMiddleware receives the required credential, and PurviewSettings is accurately described as a TypedDict.
