fix(examples): use yaml 1.1 octal numbers in kubernetes manifest files (

#5273)

Kubernetes only supports YAML 1.1, and we recently fixed a bug to read kubernetes manifests using the correct YAML version (#5184)

We accidentally did not update the example to use the old-style octal numbers. Searching for `0o` gives no further results at least in the garden repo.
