Activate linting in Jupyter Lab through LSP

[redeboer]

Linting, formatting and language navigation can be made available through jupyterlab-lsp and python-lsp-server (not Jedi). Additional support for (3rd party) linters like Ruff can be found there as well.

It might even be possible to replace jupyterlab-code-formatter with python-lsp-black. Even MyPy can be supported through pylsp-mypy.

In first instance:

python3 -m pip install jupyterlab-lsp
python3 -m pip install python-lsp-server[rope]

Then optionally for formatting:

python3 -m pip install python-lsp-black

And linting with Ruff:

python3 -m pip install python-lsp-ruff

Best to wait until jupyterlab-lsp v5 for its support for Jupyter Lab v4
