Improve setting description for default interpreter setting

[luabud]

Same issue as this: microsoft/vscode-mypy#144

Improve description of the default value of the setting. When it's set to [] it will use the Python extension's selected interpreter. If it's set to a path, it will use that value as the interpreter. See this PR: https://github.com/microsoft/vscode-mypy/pull/152/files
