configure-oidc-web-authentication linked twice in the toc file

[damienbod]

We have 2 links to the same documentation in the toc file. I think we should remove one.

- name: Configure OpenID Connect
  uid: security/authentication/configure-oidc-web-authentication

and

  - name: Configure OIDC web authentication
    uid: security/authentication/configure-oidc-web-authentication

Greetings Damien
