Utils: Fix placeholder text color for dark themes (Qt6)

Browse Source 
Qt 6 changed the color for QPalette::PlaceholderText to a hardcoded argb
value in qt_fusionPalette(), which does not work well with dark themes.

This change restores the rgb values for QPalette::PlaceholderText from
Qt 5 for Qt Creator's dark themes.
