Fix wrong example with container_op

[kim-sardine]

Hi

I've fix some example codes.

when I ran latest dsl-compile with your current example code, I got error as below

Traceback (most recent call last):

ValueError: Invalid memory string. Should be an integer, or integer followed by one of "E|Ei|P|Pi|T|Ti|G|Gi|M|Mi|K|Ki"

so I've changed GB to G

Hi @kim-sardine. Thanks for your PR.

I'm waiting for a kubeflow member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
