Update flask-appbuilder authlib/oauth dependency (apache#24516)

The dependency we have for flask-appbuilder oauth authentication
(for github/google authentication) should follow the limits
that flask-appbuilder current version has. We added authlib there
but apparently FAB currently limits authlib to <= 1.0 - we should
follow fab rather than have our own dependency here.

This has been pointed out in
dpgaspar/Flask-AppBuilder#1861
