Implement changes from CarpentryCon 2022

[bast]

For the CarpentryCon 2022 session we used two documents:

• internal: https://hackmd.io/_SEIqrzfS52SSIwe7fSMeQ
• for attendees: https://hackmd.io/@coderefinery/carpentrycon-2022-attendee

For our June 21, 2022 event we used this document:

• https://hackmd.io/@coderefinery/community-teaching-2022-summer

We have presented this session from the HackMD and not from this lesson material and a majority of the lesson material does not reflect the structure and emphasis points of the HackMD.

Follow-up actions:

• for each section and subsection which roughly matches the HackMD, create an issue with the main bullet points
• each page should start with these highlights
• save the questions from Q&A discussions from CarpentryCon and the June event as inspiration for future Q&A sessions so that we don't have to reinvent them
• save the icebreakers so that we don't have to reinvent them
