Added e2e test for site.changed webhook event

[hthorhalls]

#15537
There's a lot of API calls that can trigger a site.changed webhook event. I just cherry-picked deleting a post. If there's a more generic way to write this test I'm all ears.

Updated to only upload a single post. I don't see a squash and merge option, @naz do you want me to squash locally and push or is this something maintainers can do from the UI when merging?

Hey @halldorbjarni, we can squash our side so no worries about that 🙂 we'll get this reviewed again ASAP.
