Fixed

• (pypi) We now use the Minimal Version Selection (MVS) algorithm to select
  the right wheel when there are multiple wheels for the target platform
  (e.g. musllinux_1_1_x86_64 and musllinux_1_2_x86_64). If the user
  wants to set the minimum version for the selection algorithm, use the
  {attr}pip.defaults.whl_platform_tags attribute to configure that. If
  musllinux_*_x86_64 is specified, we will choose the lowest available
  wheel version. Fixes #​3250.
