Locate the `qemu-system-x86_64.exe` executable in WSL.
By default this will be at `/mnt/c/Program Files/qemu/qemu-system-x86_64.exe`.
Set the `SERENITY_QEMU_BIN` environment variable to that location. For example: \
`export SERENITY_QEMU_BIN='/mnt/c/Program Files/qemu/qemu-system-x86_64.exe'`
Run `Meta/serenity.sh run` to build and run SerenityOS as usual.
