Following testing with @jayunit100, there need to be some notes added to the docs

Use VirtualBox 7.0, not 6.x

Fix Host-only Network

I think this can be closed as replaced by the currently ongoing SWDT CLI sub-project

1. Experimental CLI and SDK for remote node control  #278 (see docs: Add "Quo Vadis SWDT" discussing project issues and ideas #277 for context)
2. test(cli): Start guide on testing Windows VM on Windows host #282 which actually addressed suggestion in this issue, but for SWDT CLI mode
3. VirtualBox-based setup is being replaced
