Fix make docs for multi-group API operators

The build_docs.sh script assumed all operator API types live directly
under v1beta1/*_types.go, but nova-operator moved to a multi-group
layout with types under nova/v1beta1/. The hardcoded ls glob failed
for this structure.

Replace ls with find -path "*/v1beta1/*_types.go" to discover types
in any v1beta1 subdirectory regardless of nesting depth.
