outdated README- shipped ruff and Jupyter Notebooks support in native server

[hryniewskis]

Hi,
as stated in the title, the README section about support for Jupyter Notebooks in the Native server is outdated (and at least, in my opinion, a bit confusing).

ruff-vscode/README.md

Lines 71 to 85 in 7f9ea75

	### Native Server
	The native server supports Jupyter Notebooks out of the box. Unlike `ruff-lsp`, the native server requires
	the user to explicitly include Jupyter Notebooks in the set of files to lint and format. This can be done by
	updating the [`extend-include`](https://docs.astral.sh/ruff/settings/#extend-include) setting in the Ruff configuration file.
	```toml
	[tool.ruff]
	extend-include = ["*.ipynb"]
	```
	Refer to the [Jupyter Notebook discovery](https://docs.astral.sh/ruff/configuration/#jupyter-notebook-discovery) section
	of the Ruff documentation for more information.
	[notebook document synchronization]: https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#notebookDocument_synchronization

Also, the version of Ruff, the extension is shipped with, is wrong

ruff-vscode/README.md

Line 24 in 7f9ea75

The extension ships with `ruff==0.5.7`.

According to the source code, the extension in version 2024.42.0 is shipped with ruff==0.6.1. Ruff, since 0.6.0 version supports linting and formatting Jupyter Notebooks by default (source: blog post). This also means that the native server in Ruff extension provides Jupyter Notebook Support out-of-the-box.

I will soon make a new merge request for a README update in these two places
