feat: remove "Create Zendesk Tickets for suspicious attempts" setting from Proctored Exam Settings

[santhosh-apphelix-2u]

This PR removes the deprecated “Create Zendesk Tickets for suspicious attempts” setting from the Proctored Exam Settings modal in the frontend-app-authoring MFE.
This option was previously used with PSI and Zendesk to generate support tickets for suspicious exam attempts. Since both systems are retired, the setting no longer serves a purpose and has been fully removed.

I left one comment. After we've discussed and addressed that, I think this will be good to go.
