#8129: Catch interrupted poll() in terminal console
Alternative to my own PR
#8108 - catch ZMQError in run_cell, and if it's caused by an interrupt, ignore it.
#8108 catches the exception in the blocking kernel client API, which is more complex, especially if we want to handle the timeout nicely as proposed in the comments, but it's possibly also more convenient for other users of that API. Or perhaps not - I'm not sure what makes sense for other API consumers in this case.
Fixes gh-8105
