Improve organization of runs, especially for scheduled runs

[giuseppe-sirigu]

Problem

When a scheduled job runs a new entry is added to the Notebook Jobs tab of the scheduler. If the job runs frequently (e.g., every hour) this clutters the whole table and makes it difficult to find other runs.

Proposed solution

Collect all runs in a collapsible tree where runs for a given Job are organized under the main section with the same name of the job.

Additional context

Something similar to what Databicks offers in terms of organization would make the use of this extension much more streamlined
