Add SSO option to Services

[mcalr3]

Your documentation https://github.com/linode/apl-docs/blob/main/docs/for-devs/console/services.md?plain=1#L66 mentions that there should be an option for SSO (automatic creating of oauth2 ingress) but this is not the case.

Was this an old feature which has been removed?

Thanks @mcalr3 for pointing this out.
At the moment we do not support platform SSO integration with customer services.
