Regression introduced by `cattrs v23.2.1` with `Any | None`

[jhossbach]

Takeaway from python-lsp/python-lsp-ruff#61:

I managed to track it down. There's a type in lsprotocol.types, LSPAny, typed as Union[Any, None].
Looks like there's a regression in unstructuring this type, it used to be unstructured as the runtime type, and now is unstructured as Any.

The issue is solved with cattrs>=23.2.2. Can we make the cattrs dependency more strict?

@jhossbach Feel free to provide the PR.
Add it in these two places:
https://github.com/microsoft/lsprotocol/blob/main/requirements.in : This is used for CI/CD and local development
https://github.com/microsoft/lsprotocol/blob/main/packages/python/pyproject.toml : This is the actual package deps

[jhossbach]

Gladly, just a question: Do I also need to touch packages/python/requirements.in?

[karthiknadig]

Nope, I plan on removing those as we have the dependencies described now in pyproject.toml
