Lionel Henry 3248a05406 Propagate Jupyter client errors (#40886) ...

Closes #40884

- Make IOPub task return a `Result`
- Create a monitoring task that watches over IOPub, Control, Routing and
Shell tasks.
- If any of these tasks fail, report the error with `kernel_errored()`
(which is already used to report process crashes)

This is not perfect. I did not have time to look into this but:

- When such errors happen, the kernel should be shut down.
- The kernel should no longer appear as online in the UI

But at least the user is getting feedback on what went wrong.

Release Notes:

- Jupyter client errors are now surfaced in the UI (#40884)
