Preview's sitemap still has

https://developer.okta.com/docs/guides/authenticators-okta-verify/
https://developer.okta.com/docs/guides/authenticators-okta-verify/main/
https://developer.okta.com/docs/guides/authenticators-okta-verify/-/main/

We want to see only https://developer.okta.com/docs/guides/authenticators-okta-verify/-/main/ The same for https://developer.okta.com/docs/guides/authenticators-okta-verify/ url, sitemap has all variants for it
