Turn all in-repo python examples into mini-tutorials

[nikolausWest]

After #5434, add the "Logging and Visualizing with Rerun" section to all example READMEs, in effect turning them into mini-tutorials on how to use Rerun.

I'll get started with the controlnet demo.

@BirgerMoell Hey man, I suggest using my Notion page to document what we have done and what is pending.

Here's a public link where you can edit online:
https://rerunio.notion.site/READMEs-15f2e82ab1e44b7cb62e91209ae6c8b2?pvs=4

I started updating them firstly with Intro, Rerun Types and Run sections, and later I will add the Background and Logging sections.
