Mypy-boto3

Fixed
- `[all]` String shapes are no longer interpreted as `Dict[str, Any]` (reported by sodul in 223)

Fixed
- `[all]` String shapes with a pattern are converted to `Dict[str, Any]` only if pattern fully matches JSON parsing pattern
- `[sts]` Fixed `Client.get_caller_identity` type annotations (reported by Wurstnase in 222)

Notes

G'day!

Finally, `boto3-stubs` is fully compatible with `pydantic 2.x`. `TypedDict`, `Literal`, and `NotRequired` are imported from `typing_extensions` for Python 3.7 - 3.11. However, no code changes are required on your side. The only change is that your py37-py311 projects will now depend on `typing_extensions`

With `pydantic 2.x` support, we can finally switch to a new `TypedDict` rendering with a `NotRequired` type annotation wrapper. This change decreased `type_defs.py` size by 10% and overall looks nicer.

Since the changes are quite big, please report any bugs that you encounter, and do not forget to request new features.

Keep on keeping on!
