Upgrading `4.3.2` -> `4.4.1` causes mypy type checking to fail

Hi,

to keep it short, when upgraded `4.3.2` -> `4.4.1`, mypy started throwing following errors

```
Skipping analyzing "troposphere": module is installed, but missing library stubs
or py.typed marker [import]
from troposphere import Ref

```

mypy config is
```toml

[tool.mypy]
python_version = "3.11"
strict = true
pretty = true
show_error_codes = true
warn_unused_ignores = false
plugins = ["pydantic.mypy"]
```

Pydantic version is `"==1.10.12"`
Mypy version is `mypy = "1.5.1"`

Please let me know if more information is needed.

Start with the reported mypy configuration and reproduce the upgrade from 4.3.2 to 4.4.1 using Python 3.11, mypy 1.5.1, and Pydantic 1.10.12. No source file or test is named; done means the upgrade no longer produces missing stubs or py.typed marker errors for troposphere imports.
