Revise Lite Brite Try Coding

[hfaerber]

Work through this Lite Brite Try Coding Workshop to make it ready to teach as our rebranded "Intro to Web Development workshop"

• find where the repo indicates "Turing's second shift program" that shows up in Slack previews for this link and remove that (see image in comments)
• move the starter repo into CodePen instead of repl
• update the instructions and screengrabs to reflect codepen
• when finished, update this Try Turing Eve Guide page to reflect that we're now using litebrite

[] Condense each try coding content to use only one repl. Students can copy/paste code from lesson into that one repl rather than opening new repls for different segments.

• Need to add directions for commenting out old code.
