docs: For any set of wheel files, extracts a single platform.
  
      Since a set of wheels created or downloaded on one machine can only
      be for a single platform, if any wheel in the set has a platform
      which is not `any`, it will be used with one exception:
  
      In Linux, a wagon can contain wheels for both manylinux1 and linux.
      If, at any point we find that a wheel has `linux` as a platform,
      it will be used since it means it doesn't cross-fit all distros.
  
      If a platform other than `any` was not found, `any` will be assumed
