### Description <!-- Please include a summary of the change and which issue is fixed. --> <!-- Please also include relevant motivation and context. --> This adds handling for the `temporarily_unavailable` [OAuth2 error response](https://www.rfc-editor.org/info/rfc6749/#section-4.1.2.1) by reattempting OIDC authentication. Prior to this fix all error callbacks resulted in a user-facing 500 error. It's probably not appropriate to retry on other error codes as those typically indicate either configuration issues or a more prolonged outage of the authorization service, neither of which are resolved by another attempt, hence the narrow scope of the handling added here. #### Which issue(s) this PR fixes: <!-- *Automatically closes linked issue when PR is merged.
