Update Review Alert script with contact details

[sabinevidal]

Need to update the Google ReviewAlert script with either an email address for the alert to go to, OR Add Slack integration to send a note to the Kindly channel

A single kindly email alert would be great. We child either

• setup a Google group email address which were are all subscribed to
• let the email assist code send to all our emails

I'm thinking the later would be best for now to make sure it works cc @amreenp7

Let's implement the latter right after, so that the Google group email can be an env variable

Have added emails for Amreen and Nathan in the Google Apps Script ReviewAlert
