Note that the link in zulip_update_announcements.py is not updated
so that the content in the source code reflects what users actually
received in the update announcement message.

These files are not Jinja2 templates, so there's no reason that they needed
to be inside `templates/zerver`. Moving them to the top level reflects their
importance and also makes it feel nicer to work on editing the help center content,
without it being unnecessary buried deep in the codebase.
