Automatically detect pyproject.toml file in notebook-dir (or allow to use relative paths in configuration)

I try to reference a pyproject.toml file containing pyling settings. I would like to reference it relative to the notebook directory, for example:

"pylsp.plugins.pylint.args": ["--rcfile $notebook-dir$/pyproject.toml"],

A relative instead of an absolute path would allow me to move my portable python IDE to a different folder and still keep the reference working.

However, a path variable $notebook-dir$ does not seem to be supported, yet.

Automatic detection of configuration files already seem to work for pycodestyle and flake8.

=> Please support pyproject.toml in the notebook directory as central configuration file.
