Documentviewer demo: Don't use QPdfPageSelector in Qt 6.5

The document viewer demo uses QPdfPageSelector, which is available in
Qt 6.6 but not in 6.5. This is why the demo fails to compile in 6.5.

This patch adds ifdef'ry in order to compile without QPdfPageSelector
in 6.5.

Fixes: QTBUG-111982
Pick-to: 6.5 6.5.0
