Version 2.1.1

Features

• #163 leaves the patched setup-miniconda-patched-{environment.yml} in-place
  if clean-patched-environment-file: false is given (otherwise cleans up after
  itself)
• #163 adds action outputs environment-file, environment-file-content and
  environment-file-was-patched

Fixes

• #161 restores proper ordering of channels when environment-file is
  patched
• #163 if necessary, writes setup-miniconda-patched-environment.yml to the
  same location to work with relative paths, e.g. pip: ["-r requirements.txt"]
