JSON output breaks if OCSP response is not successful

[FestiveKyle]

Describe the bug
There is an uncaught ValidationError when the OCSP response status is not successful. Most OCSPResponse properties such as certificate_status, and serial_number contain an error of OCSP response status is not successful so the property has no value.

Expected behavior
Previous versions of sslyze handled this by setting optional values to None if OCSP response is not successful. Changed here.

Python environment (please complete the following information):

• OS: openSUSE Tumbleweed 20240329
• Python version: 3.11

Additional context
