deploy: operatator.yaml -> "exec: \"yugabyte-operator\": executable file not found 

The default `Deployment` describe in `deploy/operator.yaml`, try to execute the command `yugabyte-oprtator`.

This doesn't work:
```
OCI runtime create failed: container_linux.go:345: starting container process caused "exec: \"yugabyte-operator\": executable file not found in $PATH":  unknown

```
