Witness: Fix one of the hints not being a Haiku (seriously) (#2123)

I hope this gets a prize for "Most irrelevant PR in AP history"

Explanation:
When changing the hint system on the client side to be able to auto-wrap, decisions were made about which line breaks were still explicitly important, with most of them being removed.

This hint was somewhat devalued in the process.

-. --- - .... .. -. --. translates to "Nothing", which I thought was the entirety of the joke.

However, the line breaks were actually also important, because:

dash dot, dash dash dash,
dash, dot dot dot dot, dot dot,
dash dot, dash dash dot

is a Haiku! And the hint's creator (oddGarrett I believe) said this was specifically part of the creative vision for this joke hint. They said it's fine, I don't need to change it, but I couldn't let that stand.

So, the explicit line breaks for this joke hint are back.
