fix lambda events

[drernie]

Currently conflict with Quilt indexing

you're using lambda notifications
I'm talking about EventBridge notifications
you need to enable them in bucket settings
and then create EventBridge rule that triggers lambda

[and update the event parser to match]

This is fixed in Vivos, but needs to be fixed here. Otherwise packages won't show up in Quilt searches.
(or possibly be added at all?)

1. Change CDK
2. Change event parser
3. Change test events
4. Redeploy
