feat: Add JFrog CLI outputs to JFrog login action

This commit adds the outputs `jfrog-oidc-token` and `jfrog-oidc-user` to the JFrog login action. These outputs provide the JFrog OIDC token and username generated by the Setup JFrog CLI when setting the oidc-provider-name. This allows users to access and use these values in subsequent steps or workflows.
