Context for documentation change

The MC script needs a bit of a refresh. It hasn't had an overhaul in a few years so it's about time.

• We've shut down the Virtual Coffee merch store as it was a money pit 💸
• The monthly newsletter link has changed
• All stages of the Coffee Chat event should be covered in the README
  • This will enable anyone to pick up the script and successfully MC a Coffee Chat without advanced prep (but hopefully that won't ever happen)
  • Add notes for what to expect during the breakout rooms
• Include items in the introduction instructions that we've added over time and stress that sharing is optional
  • These changes should be reflected in the Room Leader and Notetaker READMEs
• Give clearer instructions on what information is needed from a first time attendee
  • These changes should be reflected in the Room Leader and Notetaker READMEs
• Swap newsletter link in closing announcements for website events link, as the newsletter is often incorrect
• Add reference to #questions-about-vc Slack channel and LinkedIn page
• Remove additional references to newsletter and podcast since that's covered in the block of links

Proposed solution

• Remove all references and links pointing to the store
• Change newsletter to correct link
• Add LinkedIn reference
• Add reference to #questions-about-vc Slack channel
• Make section header names more detailed
• Rewrite portions that are confusing or too wordy
• Fix grammar and typos
• Use GFM features
• Lint markdown

@meg-gutshall I don't think VC docs has any link to the store. Do you mean to create an issue at the vcio repo?
