Pull Request Overview

This PR migrates the Authorization cmdlet module to use AutoRest v4 by updating generated documentation, metadata, and assembly info to align with the new code generator and add JSON-based parameter sets.

• Updated many cmdlet markdown files: removed outdated -InputObject sections, introduced CreateViaJsonFilePath/CreateViaJsonString parameter sets, adjusted Parameter Sets annotations, and standardized output model references.
• Updated Az.Authorization.md and module metadata: bumped Module Guid, added new Update- cmdlets entries, and increased Az.Accounts dependency version.
• Added a generated AssemblyInfo.cs for assembly metadata and versioning.
