qdoc: Breadcrumb menu bug if \module, \qmlmodule clash

QML and C++ modules are documented by different commands:

• \module, \inmodule for C++
• \qmlmodule, \inqmlmodule for QML

ANyhow, the generated breadcrump menu seems to confuse these, for instance in Qt Multimedia, where there's both a \module QtMultimedia and a \qmlmodule QtMultimedia.

For QCamera, the breadcrump menu reads

Qt 6.3 > Qt Multimedia > C++ Classes > QtMultimedia > QAudioBuffer

While it should be

Qt 6.3 > Qt Multimedia > C++ Classes > QAudioBuffer

("QtMultimedia" actually links to the QML index page)
