Fix schreenshots test: Part 1

Summary:
Update all the screenshots for pictures in the Tutorials of Docs; not including images in Overviews.

Plan to add tests for images in Overview in another diff.

Test Plan:
Need more eyes to double check since there are many image comparisons.

• Run docs.dagster.io locally to see if images match texts.
• Compare images diff under under docs/next/public/assets/images/tutorial
