[BUG] many notebooks have a broken link after docs upgrade in the register() example cell

[DataBoyTX]

Many demo notebooks have the following broken link in the register() example cell: : # For more options, see https://github.com/graphistry/pygraphistry#configure

e.g.

import graphistry

# To specify Graphistry account & server, use:
# graphistry.register(api=3, username='...', password='...', protocol='https', server='hub.graphistry.com')
# For more options, see https://github.com/graphistry/pygraphistry#configure

need to update README.md to have this, or update notebooks to point to new readthedocs link.
