Have Session Menu also change default shell for VS Code's integrated terminal

Issue Description

Is this an oversight or by design?

Even though the PowerShell Integrated Console is PS 7, PowerShell isn't.

[TylerLeonhardt]

That is provided by VS Code, not the PowerShell extension. It's configurable though via the command pallet.

[PrzemyslawKlys]

But is it possible to bind it so it switches when you switch? I guess from my perspective it would be cool to have?

[TylerLeonhardt]

I see. I guess we could do that but I would want more user feedback saying they want that... and it would need to be configurable because I'm not sure everyone would want that behavior.

[rjmholt]

Yeah I could see us getting a whole bunch of cranky bug reports about that
