I've renamed the quickguide doc directory to getting_started and updated the docs to use MultiPhysics.

I've replaced just a few of the SV GUI images with the latest SV version, will replace the others later.

I've removed the Getting Started CFD Simulation sub-section, will later add that to the CFD Simulation guide.

I think @ryanspilker is working on this so I have assigned him.

@ryanspilker We also need to provide more details about using WLS2.

@ryanspilker What's the status of this ?

@ktbolt I am continuing work on the Getting Started simulation documentation including adding new screenshots and instructions. This work overlaps with the solver tutorial updates tracked in #91. I will coordinate the relevant changes here as this work progresses.

The WSL2-specific guidance is now separated into #103 so it can be developed and reviewed independently. @justran-csuf and I are assigned to that issue. He will lead the platform-specific guidance if his availability permits, and I will help to integrate the completed tutorial into the Getting Started documentation.
