fix: orphaned pages

[vinckr]

fixes the following orphaned pages and adds them to the sidebar

• https://www.ory.sh/docs/kratos/guides/e2e-integration-tests
• https://www.ory.sh/docs/kratos/guides/security-questions-best-practice
• https://www.ory.sh/docs/kratos/manage-identities/export-user-accounts-identities
• https://www.ory.sh/docs/kratos/self-hosted/email-http
• https://www.ory.sh/docs/kratos/self-hosted/mail-courier-templates
• https://www.ory.sh/docs/search

I was not sure about /search, but the last commit adds it to the sidebar as well.
After this there is only https://www.ory.sh/docs/oathkeeper/oauth2-token-introspection-hydra (a WIP doc) and the /debug and /fallback docs left (not sure what to do about those, have to investigate how they are used still).
