Breakdown updates for upcoming movie events.

Things are happening very fast now and the latest followups we did, points out more information about when the MCU events are taking place in the timeline (this is one of the primary reasons for why this list also exists).

As of today – we are updating both the API-data and the current MCU timeline list with this information – we have dates for both Shang-Shi and The Eternals for when in the MCU they take place. To make it easier, there are now also direct links to the stated sources at the prior timeline website.
