Setting that we will be using for configuring the interpreter for the LSP server.

                "<pytool-module>.interpreter": {
                    "default": [],
                    "description": "When set to a path to python executable, extension will use that to launch the server and any subprocess.",
                    "scope": "window",
                    "items": {
                        "type": "string"
                    },
                    "type": "array"
                },
