[Development] Nominating Denis Shienkov for Approver status

[André Hartmann]

I'd like to propose the nomination of Denis Shienkov for Approver
status.

Denis has been the maintainer of QtSerialPort for a long time now.
He also formed the architecture of QtSerialBus and provided several CAN 
plugins there. He further contributes to other parts of Qt and QtCreator 
and is actively reviewing other changes (for example he has 
constructively improved a lot of my changes to QtSerialBus).

This is his own Gerrit dashboard:

And these are his reviews:

Best regards,
André
