Microsoft Copilot (Microsoft 365): [Copilot Extensibility] Delete Schema Properties via Copilot Connector APIs

We’re adding support for property deletion in custom Copilot connectors, giving admins and developers more control over schema evolution. With this feature, you can: * Use Copilot connector APIs to delete or drop individual schema properties that are no longer needed. * Keep your connector schema clean and up-to-date without requiring full re-ingestion. * Reduce developer overhead and simplify maintenance workflows as your data models evolve.
