The default behaviour for container image pulls depend on different values
such as image tag usage and its value.
See https://kubernetes.io/docs/concepts/containers/images/#imagepullpolicy-defaulting
It leads to an unintended behaviour for this Helm Chart. Kubernetes
will always pull the image for init containers when using the `latest`
Gitea image, even if `Values.image.pullPolicy` defines a different value
for the runtime container.
