Update/Install: Reject invalid messages in the Shiny Updates postMessage handler.

Browse Source 
This prevents conflicts with third-party messages (e.g. sent by browser extensions). The updates script expects a specific JSON-encoded message and now bails early if it's not valid JSON.

Fixes #37125.
Built from https://develop.svn.wordpress.org/trunk@37976
