Mention VS Code support in pixi docs

[cdeil]

Problem description

I think since recently (see #411) pixi supports VS Code.

Could you please mention this at https://pixi.sh/latest/ with some instructions how to use it properly?

Are there any steps / gotchas, e.g. to exclude the .pixi folder from project search or anything else to make it work well?

Currently only support for JupyterLab, Pycharm and RStudio is mentioned:

It seems VS Code can't detect the pixi env automatically. I had to first create a python script and use VS Code to enter the python interpreter path manually. After that, creating a Jupyter Notebook can select the pixi python interpreter.
