There are only a handful of non-JSON webhooks that wouldn't
benefit from the notify_bot_owner_on_invalid_json feature.
Specifically, these are the webhooks where the third-party product
uses another format, whether it be HTML form-encoded, XML, or
something else.
Tweaked by tabbott to correc the list of excluded webhooks.
These are the straightforward ones.
Note that there is a line in zerver.lib.test_classes.build_webhook_url
that lost test coverage. That's because most of our tests test using
stream messages so the webhook URLs being tested always have a query
parameter. So the line that accounts for there being no query
parameters never gets called, which is fine, but we should still
keep it.
This is just a basic Dropbox webhook integration. It just
notifies a user when something has changed, it does not
specify what changed. Doing so would require storing data,
as Dropbox API was created mainly for file managers, not
integrations like this.
