[ci skip] Improve #find_in documentation.

The previous documentation version listed only the default
registered extensions. This was misleading because if more extensions
get registered with
<tt>SourceAnnotationExtractor::Annotation.register_extensions</tt>,
they would be also taken into account. By saying that we consider
all registered extensions we document what happens in reality.
