quotes around numbers for the ports definitions

[fenio]

This is 2nd approach for #10969 so below is mostly copy from previous attempt.

What this PR does / why we need it:

I've just wasted 2 hours with errors like "var substitution failed for 'ingress-nginx-private': json: unsupported type: map[interface {}]interface {}" because examples shown in values.yaml don't include quotes for port numbers used for tcp/udp services. It's pretty common issue in YAML world when key is numerical. Just want to avoid same headache for others.

Hi @fenio. Thanks for your PR.

I'm waiting for a kubernetes 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.
