QtWebEngine and QtPdf are not installable on Qt 6.8.0

[aa-bamboo]

QtWebEngine and QtPdf were removed from standard Qt distribution as modules and moved into "extensions" since Qt 6.8.0 (LTS).

Qt 6.8 release notes

Example (from repository):

Before Qt6.8:

<package name="qt.qt6.632.addons.qtwebengine" displayname="Qt WebEngine" version="6.3.2-0-202209071847"/>
<package name="qt.qt6.632.addons.qtpdf" displayname="Qt PDF (TP)" version="6.3.2-0-202209071847"/>

After Qt6.8:

<package name="extensions.qtpdf" displayname="Qt PDF" version="6.8.0-0-202410030748"/>
<package name="extensions.qtpdf.680" displayname="Qt 6.8.0 " version="6.8.0-0-202410030748"/>
<package name="extensions.qtwebengine" displayname="Qt WebEngine" version="6.8.0-0-202410030749"/>
<package name="extensions.qtwebengine.680" displayname="Qt 6.8.0 " version="6.8.0-0-202410030749"/>

Unfortunately now it's not possible to install these package using install-qt-action.

Furthermore it's not installable even by aqt (which is used under the hood).
