Specify binaries to use in the Readme

[RubyRaven6]

I've seen quite enough people get tripped up about the difference between the Windows and Linux binaries (including on occasion, more experienced hackers that don't normally use Windows). Anyone who didn't are likely: - Experienced enough to know that WSL is doing the compiling (vanishingly small comparatively) - People who watched Archie's tutorials where he specifies downloading the Linux binary when using WSL (the bulk of new users coming into decomps) - Guessed the Linux binary by accident (not as small as the first one, but likely still small)

It seems a bit shaky to rely on these, so it may be good for UX to include it.
