...from submariner-operator in lieu of using Go embed functionality.
The charts project needs to obtain the RBAC and CRD yaml files from the
submariner, submariner-operator and mcs-api projects. To achieve this,
define a simple Go file that statically references the packages
containing the desired embed.go and yaml files. The generate-yamls.sh
script uses 'go mod' commands to create the go.mod file and vendor
directory, which also downloads the yaml files.
