py-zconfig: updated to 3.6.0

3.6.0 (2021-05-19)
==================

- Added support for Python 3.8, 3.9 and 3.10.  This primarily involves
  avoiding the new-in-3.8 validation of the format string when using the
  'safe-template' format style, since that's not supported in the Python
  standard library.

- Added ``ZConfig.pygments`` module containing a lexer compatible with
  the ``pygments`` library.  Made discoverable via an entry point; use
  **zconfig** as the highlight language for ``code-block`` directives in
  Sphinx documents.
