Making the RemoveEnv method work across all containers in a deployment

[AdamSaleh]

Making the RemoveEnv method work across all containers in a deployment, instead asserting there is exactly one container.

What type of PR is this?
/kind failing-test

What does this PR do / why we need it:

When installing gitops-operator-bundle directly through operator sdk, there seems to be more than one container in the deployment. Making the utility function work across all containers makes the code more robust.

Hi @AdamSaleh. Thanks for your PR.

I'm waiting for a github.com 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-sigs/prow repository.
