In the OpenID flows, the "CfTurnstileSitekey" wasn't populated, which caused those flows to fail if using Turnstile as the Captcha implementation. This adds the missing context variables, allowing Turnstile to be used in the OpenID flows. (cherry picked from commit 0d24c9f383255605d68a92cc5f087c3f16a1d735)
