This implements a fake OIDC server, which intercepts calls to the HTTP client. Improves accuracy of tests by covering more internal methods. One particular example was the ID token validation, which previously mocked. This uncovered an incorrect dependency: Synapse actually requires at least authlib 0.15.1, not 0.14.0.
