Dark themes not used properly in virtualbox - light grey text on slightly whiter grey

[Ian]

Ubuntu MATE 22.04 does a really good job of having (almost) everything reflect the chosen theme.

One of the exceptions is virtualbox 6.1, where having a dark theme for the system results in virtualbox showing light grey text on what remains a slightly whiter (rather than dark grey) background.

When one of the virtual machines is selected, its name and power state are - on my theme - a medium light green, but as the text is still light grey, it is still hard to read.

In the virtual machine's details, some text appears blue when moused over otherwise it's the light grey on slightly lighter grey.

virtualbox-6.1 is proprietary and not supported via the Ubuntu archive. VirtualBox does not honour the QT_QPA_PLATFORMTHEME environment variable Ubuntu MATE exposes to facilitate Qt/GTK theme integration.

Upstream virtualbox issue tracker shows that this will not be fixed.
