Add screenshots to Lineage Doc

Context

A lot has evolved and changed in our Data Lineage view of the Cloud UI since we initially launched it and wrote this doc: https://docs.astronomer.io/astro/set-up-data-lineage

As visual of an experience as it is, we don't currently have any screenshots.

Ask

Not sure exactly what we need, but to close this GitHub issue I think it's a few things:

1. Do an evaluation of all the views in lineage and decide which ones deserve a screenshot. Work with PM (@jlaneve + @harels) on this.
2. Consider if GIFs would be better in any of those instances.
3. Add those visuals to the doc.
