Enabling authentication in Red Hat Developer Hub in the Admin guide lists three authentication providers. However, the subsequent proc modules do not align with the providers listed in the assembly. 

To resolve this issue, perform the following actions: 

• Replace the Enabling the GitLab OAuth authentication module with Enabling the GitHub OAuth authentication provider
• Add an Enabling Keycloak with OIDC authentication module to the Enabling Authentication assembly

NOTE: Check the repo and the Configuring plugins in Red Hat Developer Hub guide for existing Keycloak content and add/embed/link if applicable.
