Include link to health check page with Slack webhooks

I’m a big fan of being able to finally use slack webhooks for health check notifications now :slightly_smiling_face:
I think I would like it a tad more if those webhook messages also included a direct link to the specific health check such as<account>/<zone>/traffic/health-check-analytics?healthcheck-name=<health-check-name>&region=GLOBAL.

Currently the message already includes a decent amount of info, but having the health check link in it would be pretty useful and also save some time, especially when for example a health check notifies you about prod being down :sweat_smile:
