Subject: [PATCH] feature: add analytics session lenght data to view (#2550)

- Found that it wasn't possible to replicate the ["Average time spent"](https://metabase.editor.planx.uk/question/15-average-time-spent?flow_id=0e9d79ec-9cf3-497d-a1a1-8e70469bb52d) card without analytics session length data
- Add analytics.ended_at to the view
- Add time_spent_on_analytics_session_in_minutes to the view
