Broken or outdated links in the README
The current README points to documentation at https://gw.readthedocs.io/ligo-gracedb/ and https://gw.readthedocs.io/projects/ligo-gracedb/en/latest/contributing.html, which both lead to an error page. It also points to the old repository https://git.ligo.org/lscsoft/gracedb-client.
I can open a merge request to fix all of this if somebody points me to the current documentation.
