Is an embedded real-time OS like VxWorks still used in this role on this kind of mission today, or is a general-purpose OS like Linux used instead?

Pretty sure VxWorks is still used today for a lot of spacecraft; Curiosity[^1] and at least at one point the SpaceX Dragon capsule[^2] it looks like.

Yes, lots of spacecraft use traditional RTOSes like VxWorks, RTEMS, ThreadX, uCos, etc. Keep in mind that there are many computers on a large spacecraft - attitude control, command and data handling, instruments, and other microcontrollers.
