Description & steps to reproduce

Problem

Kurtosis seems to blow up when using a sha256 string for a docker image. This is a valid string and works fine in kubernetes.

There was an error interpreting Starlark code 
Evaluation error: Cannot construct 'ServiceConfig' from the provided arguments.
        Caused by: The following argument(s) could not be parsed or did not pass validation: {"labels":"An error occurred validating service config labels 'map[ethereum-package.client:geth ethereum-package.client-image:ethereum-client-go@sha256-2246c2df2eef7e1f88213cc6b98c3f180ddfd6c16a96e634143e47a3de2d313c ethereum-package.client-type:execution ethereum-package.connected-client:prysm]'\n\tCaused by: Invalid service config label value 'ethereum-client-go@sha256-2246c2df2eef7e1f88213cc6b98c3f180ddfd6c16a96e634143e47a3de2d313c'\n --- at /home/circleci/project/container-engine-lib/lib/backend_interface/objects/service/service_config_validators.go:27 (ValidateServiceConfigLabels) ---\nCaused by: Expected label string 'ethereum-client-go@sha256-2246c2df2eef7e1f88213cc6b98c3f180ddfd6c16a96e634143e47a3de2d313c' to be a Kubernetes label value, instead it failed validation:\nmust be no more than 63 characters\n\na valid label must be an empty string or consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyValue',  or 'my_value',  or '12345', regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])?')\n --- at /home/circleci/project/container-engine-lib/lib/backend_impls/kubernetes/object_attributes_provider/kubernetes_label_value/kubernetes_label_value.go:42 (ValidateKubernetesLabelValue) ---"}

Error encountered running Starlark code.

To reproduce:

kurtosis run github.com/kurtosis-tech/ethereum-package --args-file ./testing/kurtosis/presubmit.yaml

presubmit.yaml can be found in the gist below.

Desired behavior

We must have consistency and reproducibility in our CI and will not accept using docker labels. We must use sha256 strings for our docker image definitions and this should work fine.

What is the severity of this bug?

Critical; I am blocked and Kurtosis is unusable for me because of this bug.
