Relax constraints on jupyter-core and ipywidgets (#9364)

* Relax constraints on jupyter-core and ipywidgets

These were originally added in #9105 and #9272 respectively, but the
original problem package `seaborn` has released since then, which may
have fixed things.

* Fix suppressions for Jupyter warnings

This removes some now-unnecessary suppressions from image-related
packages, and adds the new suppression for the pyzmq problem, which is
Jupyter's domain to handle.  The extra environment variable in the
images test run is to eagerly move to new default behaviour starting in
jupyter-core 6; there is no need for us to pin the package too low,
since this warning is just encouraging people to proactively test the
new behaviour, and it doesn't cause our suite problems.

* Use correct YAML syntax

One day I'll remember this when writing environment variables in YAML
files, but it's not this day.
