Pull Request Overview

This PR provides a comprehensive update for the Data Migration Management SDK with a version bump to 10.1.0b2. It standardizes type annotations (e.g. replacing IO with IO[bytes] and using IOBase for type checks), updates the default API version to "2025-03-15-preview", and adds new operation groups for Mongo-to-Cosmos DB migrations and migration services.

• Updated type hints and parameter validations across multiple operations
• Integrated new operation groups into the client and updated client initialization logic
• Removed deprecated vendor utilities and bumped the package version
