Add dropdowns to all chapter for key takeaways and environment setup

[LuisHeinzlmeier]

I added two types of dropdown boxes to all the chapters:

1. Key takeaways:

• Each bullet point gets its card, which links to the corresponding paragraph when clicking.
• 1-5 bullet points for each chapter.

2. Environment setup:

• Explains how to set up an environment with the corresponding yml file.
• Loads default_text_env_setup.md for the "steps"-tab and the corresponding yml file for the "yml"-tab.
• I excluded this box from a chapter if the text had no code (e.g., introduction chapters).

Please have a look when you have time :)

This is awesome!

A few requests:

1. Could we spin your observations concerning missing and too general environments into a follow up issue, please?
2. I wonder whether we should have the boxes after the chapter title. What do you think?

There might need to be another step before that which explains how to install Conda. Could you add one sentence on that, please?

1. done! Missing yml files for every chapter/notebook #336
2. Yeah, I think I am generally not super happy with the box yet. I think the location is good at the beginning, but the box is very dominant!
   What do you think about this design with a small badge/button on top referencing the box at the bottom?
   Here, I added the box after the title to see what I would look like.

Both options are great! But in both cases, I would keep it as a dropdown. It just makes the chapters appear less long. It is however a bit weird to me that the environment setup is at the bottom for the scrollable option. I know that we have the session-info at the bottom but that seems to be more common than a "how to setup the environment guide".

Should we ask more people for feedback? We can ask in the big sc-best-practices channel. We can also make a decision among the three of us.

Finally! 🎊
