DOC: config: mention that a single monitor-uri rule is supported

It was reported in issue #1059 that when multiple monitor-uri rules are
specified, only the last one is used. While this was done on purpose
since a single URI is used, it was not clearly mentioned in the doc,
possibly leading to confusion or wasted time trying to establish a
working setup. Let's clarify this point.
