chore: Remove cvss.proto in containeranalysis from being excluded. (#…

…3213)

The protoc generated files for cvss.proto are outdated for
containeranalysis, we are going to update them in
googleapis/google-cloud-java#11155. This
cvss.proto was exclude before because the whole [v1beta1
version](https://github.com/googleapis/google-cloud-java/blob/main/java-containeranalysis/.OwlBot-hermetic.yaml#L30-L36)
was not configured to be updated.
