Add link to download micro:bit Scratch cards to the microbit extension page. Place it after Starter Projects, before Troubleshooting.

Here is the PDF (Note: PDF may get updated - Natalie and KO will confirm )

Seems simple. We could borrow the scratch cards section on the ideas page, or design something more Microbit-specific.

@ntlrsk I moved this to May due to some scheduling pressure. Is that ok with you?

[benjiwheeler]

Labeling this as 'needs discussion' pending @carljbowman clarifying plans.

Update: still waiting on further discussion from the team. Maybe this should be more explicitly put on one person's plate, or backlogged?

@benjiwheeler I added this to our weekly design meeting agenda. Will follow-up after discussion.

@kathymakes Looks great! Let's move forward. My only nitpick would be to remove the duplicate trail of "S"s in the illustration, but I'm happy to defer to your judgement. Let's move forward with implementation.
