QtQuick.VirtualKeyboard docs: [since] marker is broken on methods and signals

The [since …] marker on some methods and properties signal looks like part of a header instead of right-aligned side-note attribute.

Some affected items:

• https://doc.qt.io/qt-6/qml-qtquick-virtualkeyboard-inputengine.html#traceBegin-method
• https://doc.qt.io/qt-6/qml-qtquick-virtualkeyboard-inputpanel.html#externalLanguageSwitch-signal
• https://doc.qt.io/qt-6/qml-qtquick-virtualkeyboard-inputengine.html#patternRecognitionModesChanged-signal

Is it just a typo in docs code, or a common bug of all such attributes?
