Update script to use importlib_resources (#6949) 
To avoid a deprecation warning, this change updates scripts/update_api.py
to use 'importlib_resources' instead of 'pkg_resources'.

See https://setuptools.pypa.io/en/latest/pkg_resources.html and
https://importlib-resources.readthedocs.io/en/latest/migration.html for
more information.
