[OCPBUGS#54694]: Fix capitalization issue with updateMode values

[chuckersjp]

Current docs list a number of options for the updateMode parameter of the VerticalPodAutoscaler that are listed as lower case. However using lower case for these values will result in an error from the server and fail to create said VPA. This PR fixes those values.

Version(s):

OCP Docs for 4.12 though Current Release. This issue actually appears earlier as well.
Issue:

https://issues.redhat.com/browse/OCPBUGS-54694

Additional information:

Upstream source implies that only capitals are permitted:

Hi @chuckersjp. Thanks for your PR.

I'm waiting for a openshift 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.

@chuckersjp @asahay19 I'm sorry. I didn't see that Chuck created this PR. I created another PR to address the same issue. Mind if we go with that one?
