Show a dialog when user's dont select an interpreter

[MichaReiser]

This is something that has come up often with Ruff's extension and I suspect will also become a problem with ty. The issue is that the extension "hangs" if the user doesn't select a python interpreter in the Python extension.

A possible easy fix here could be to let "resolveInterpreter" and a timeout promise race and show a message (and fallback to the bundled version?) if no interpreter is selected within x seconds.

Can you say what "hangs" mean? I think the extension would just quit and display a "Python interpreter not found" warning in the toolbar.

Combine this with #5, we might be able to improve the experience here.

What I mean by that is that Ruff doesn't start. The extension waits until the user selects an interpreter. I wonder if it would be a better experience to, after some delay, start the server anyway and restart ruff/ty when the user selects an interpreter.

Combine this with #5, we might be able to improve the experience here.

I agree, that this might help but I think we need to assume that most users have the Python extension installed.
