- Added a new test case `resp_bad_embedded_cert` in
`create_ocsp_test_blobs.py` to test OCSP response with an unusable
internal cert that can be verified in Cert Manager.
- Updated `test_ocsp_response_parsing` in `ocsp.c` to include the new
test case.
- Ensured the new test case checks for proper handling of OCSP responses
with incorrect internal certificates.
