Doc: Re-add .qml files as example sources

Commit dabf5d2e fixed a documentation issue with QML type inheritance
by excluding .qml files from the documentation build. A side-effect is
that example documentation pages do not list .qml files as part
of the example project.

Instead of excluding all .qml files, simply exclude '*.qml' from the
list of source file extensions. This way, .qml files are still
considered to be part of examples.
