Fix qdoc warnings

As JavaScript parsing issue got fixed , the limit was
not changed, meaning there where 4 "unused" warnings
possibilities. In the meantime another change
e6a13d97898f3f4b19f61006d0716ca9e1b9f037
was merged which had 3 qdoc issues, which got therefore
unnoticed.

Fix those issues.

Do not use underscore in example name and rename push_notification
to push-notifications (like qtbase network-chat).
