@rnorth Apologies richard for the random tag, but do you have any idea how authors will get notified of this PR? It's my first time contributing to this open-source library |

Add py.typed marker files to core and all module packages to indicate type information is available. This enables type checkers like Pyright and mypy to recognize and validate type hints in testcontainers packages. Resolves "Stub file not found" errors when running type checkers on code that imports testcontainers modules.

Summary
Adds py.typed marker files to all testcontainers packages to comply with PEP 561 and enable type checking support.
Motivation
Without py.typed markers, type checkers like Pyright and mypy report "Stub file not found" errors when importing testcontainers modules, even though the code has inline type annotations.
Changes
Testing
Verified that type checkers no longer report missing stub file errors:
