User story
As a developer of Fleet's website,
I want to see how changes to the website might affect our analytics
so that I can know when changes to the website have a negative/positive effect on website users.

How?

Add a way to automatically/semi-automatically annotate Google Analytics reports when changes are made to the website.

• Add a new label to the Fleet repo (e.g., ~annotated change).
• Update the website's GitHub webhook to automatically apply that label if a pull request changes certain pages on the website (e.g., homepage, pricing, landing pages).
• Update the website's GitHub webhook to send requests to Zapier when a pull request with the new label is merged.
• Create a new zap that uses the GA4 API to create an annotation on reports that contains the name of the PR and a link to it.
