A CI action to make sure that our score on Mozilla Observatory for HTTP security doesn't go down would be useful

I was just thinking about this, the CI isn't really that useful because we don't have any kind of CD pipeline to actually deploy previews for PRs and automated after a commit. I would manually have to run the CI after I deploy it to see it reflect changes, which at that point I'll just do it myself on the site.
