🌱 Fix adding appended list directly causing changing previous value

[fmuyassarov]

Baclport of #5670 to v1alpha4 API in release-0.4 branch.

What this PR does / why we need it:

Original paths will use appended list directly, this works fine when there is fewer recursion, or there is only one for loop for the diff, but if there are multiple loop, second loop would override the first added array.
Thus I'm creating a new tmp array to do a deepcopy, then add this appended value into allPaths.

Hi @fmuyassarov. Thanks for your PR.

I'm waiting for a kubernetes-sigs 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.
