Increase the number of allowed Certificate Authority references #4087
Description
What would you like to be added:
I propose increasing the maxItems validation limit for the caCertificateRefs field in FrontendTLSValidation:
Current value: 8
Proposed value: 32
Why this is needed:
The current limit of 8 is too restrictive for certain use cases where a larger number of certificate authorities must be referenced to support diverse integrations. Raising the limit to 32 provides greater flexibility while maintaining reasonable bounds for validation.
