The command Terminal: Attach to Session exists on remote but didn't work in local when we added reconnect since terminals are pretty short lived after the window goes down. I was thinking this would be good to support if the window crashed such that the processes can be recovered, plus we could explore configuring the live time and whether terminals should be closed on window close in the future.

Repro:

1. Open 2 windows
2. Open terminals in each
3. Type in each terminal to differentiate them
4. Kill the renderer process for one of them
5. Running Terminal: Attach to Session should allow recovering of the terminals after ~4 seconds.
