Updating jsonschema and jupyter_events dependencies

[bollwyvl]

Problem

The current pin to jsonschema <4.18.0 makes this package incompatible with jupyter_events >=0.7.0, and the 0.6.x line is unlikely to get further updates barring severe security issues, nor is the 0.7.0 line likely to backpedal on its upstream deps.

As jupyter_events is a hard dependency of jupyter_server, this will become a larger issue in the future.

Proposed Solution

Either:

• raise bottom pins to:
  • jsonschema >=4.18.0
  • jupyter_events >=0.7.0
• determine how to support the entire range (significantly harder)

And then:

• declare minimum versions, removing top pins
• test against the minimum declared versions (at least in CI)
