The current link is https://pulpproject.org/pulp_rpm/restapi.html/#tag/Repositories:-Rpm/operation/repositories_rpm_rpm_create

THe link to the REST API is broken. The correct link is https://pulpproject.org/pulp_rpm/restapi/#tag/Repositories:-Rpm/operation/repositories_rpm_rpm_create

We should do a search and replace in various repos.
