Mini 1: Add 'break moments' where a mini workshop should pause when delivered on Zoom

[jlooper]

Context

Now that we are teaching online, we need to designate where we break out into Zoom breakout rooms to work together to help students debug their code.

Expected Behavior

Add an emoji callout that is visually arresting to "stop! breakout!" - but make it cute :)

Acceptance criteria

Add about four of these to Mini 1, as is appropriate for the flow of the content.

[jlooper]

I'll take this one :)
