Remove non-resolving OCSP endpoints from APIM VNet docs.

[hariscats]

Summary

Updates APIM VNet documentation to remove invalid OCSP endpoints and align with current Microsoft CA infrastructure.

Changes

• Remove ocsp.msocsp.com (retired; no longer resolves).
• Replace oneocsp.msocsp.com with the correct oneocsp.microsoft.com.

Rationale

Two listed OCSP hosts are no longer functional or documented elsewhere. The Microsoft page “Azure Certificate Authority details” includes a changelog entry (dated 8 October 2024) stating that ocsp.msocsp.com was removed from Microsoft’s CA/CDP/OCSP endpoints list. Cleaning them up prevents incorrect allowlists and reflects current certificate-validation behavior.

Impact

Improves accuracy of outbound network requirements; no change to APIM functionality.
