    gnu: python-pytest-6: Fix version via setuptools-scm.
    
    * gnu/packages/check.scm (python-pytest-6): Fix indentation.
    [phases]{fix-version}: Rename to...
    {pretend-version}: ... this.  Use the supported setuptools-scm mechanism to
    manually fix the version string, as suggested upstream.
