doc: document or link to DEPENDENCIES TARGET and IMPORTS TARGET

Add a link or document DEPENDENCIES TARGET and IMPORTS TARGET in https://doc.qt.io/qt-6/qt-add-qml-module.html#declaring-module-dependencies .

There is currently only a note

Note: Since Qt 6.8, it is possible to pass a target name to IMPORTS and DEPENDENCIES. See QTP0005 for more details.

but its hard to notice (there is already an unrelated note between the description of DEPENDENCIES and this note).

Add this information to the description of IMPORTS and DEPENDENCIES instead of having this information being a note.
