Doc: Mention plugin dependencies in the deployment guide

As the plugin can be used also in widgets-based application, discuss
the deployment of required libraries for such applications.

Replace the qmake-specific notation in listed paths to make the
guide build-system agnostic, and remove specific mentions of the
major Qt version.

+\section2 Dependencies
+
+The Qt Virtual Keyboard plugin \e (qtvirtualkeyboardplugin) has a dependency
+to the \e {libQt\QtMajorVersion}\e{\VirtualKeyboard} library. In addition, the
+plugin depends on Qt Quick. Therefore, a stand-alone application based on
+\l [QtWidgets] {Qt Widgets} must deploy also the
+\e {libQt\QtMajorVersion}\e{Quick} library and its dependencies in order to
+use the virtual keyboard.

 \section1 Integration Method
 
 Qt Virtual Keyboard currently supports two alternative integration methods
 for using the plugin:
 
 \list
-    \li \c Desktop: requires no changes to existing applications.
-        The virtual keyboard is available to all of the Qt 5 applications
-        in the system.
+    \li \c Desktop: requires no changes to existing applications. The virtual
+        keyboard is available to all Qt applications in the system.
 
         In this integration method, the keyboard is shown in a dedicated
         top-level window.
