Create a new CA set version in the CA set specified by caSetId. When creating a new version, the API compares the certificates and SHA-1 provided in the request with the existing versions in the CA set. If another version exists with fingerprints for the same certificates, a 422 response provides a link to the version. If the allowInsecureSha1 option differs between the versions with the same certificates, they're still considered the same CA set version. This prevents creating duplicate CA set versions.
