There are two issues with the workflows command:

1. only assessment job is shown in the list, even though we have to show all of the relevant jobs - assessment, migrate-groups, remove-backup-groups, ...
2. state is None, but it should have been failed.
3. Started should show a bit more human-friendly value, like "34 minutes ago"

$ databricks labs ucx workflows

Step        State  Started
assessment  None   1.705400967017e+12

this is the result on a fresh installation for a workflow that is currently running:

and this is for the assessment job that finished - the UCX is not quite good.
