Fix docs to explain the new type syntax for QML methods

[ChangeLog][QtQml] It is now possible to specify types for method
parameters and their return value in QML (basic and object types), using
TypeScript-like syntax with a colon separator. The syntax for QML
declared signals supports the same style.

This change also adapts the remaining snippets and docs to the "fresher"
qml signal parameter syntax.
