Type annotations for boto3 DatabaseMigrationService

mypy-boto3-dms provides PEP 561 compatible type annotations (stubs) for the `boto3` AWS Database Migration Service (DMS) client. This package helps static type checkers like Mypy, Pyright, and IDEs (VSCode, PyCharm) provide better autocompletion, error detection, and overall developer experience when working with `boto3`'s DMS client. It is currently at version 1.42.80 and is frequently updated to align with `boto3` releases.
