Shorten size of slack messages

[nitrocode]

Seems that the event JSON is the largest portion of the screen. I couldn't even shrink my desktop screen enough to show the full event.

We could probably reduce the message by omitting the event json and maybe adding a link to the aws-console page for the full event json?

Or we can use the secondary attachments in slacks block kit. It shows the first 10 lines and adds a show more button to see more.
