Use "curl" to trigger rtd.org webhook with http basic auth

For some reason (unknown really for us) triggering webhook with http
basic auth using Ansible's uri module started recently failing when it
is run on some operating systems, like e.g. Ubuntu Noble.

Let's switch to use curl command directly to trigger that webhook
instead.
