py-dominate: updated to 2.9.1

2.9.1
Allow dominate to work in async contexts

2.9.0
Modernize setuptools support to use pyproject.toml

Replace the obsolete `setup.py` script and `setup.cfg` configuration
file with the modern PEP 621 `pyproject.toml` metadata.  This also
implies replacing the custom version/long-description grabbing logic
(that is broken with Python 3.12) with the features nowadays built-in
in setuptools.
