Add indention to forwardConfig

[jacurtis]

This clarifies to the reader that targetGroups and TargetGroupStickinessConfig are both within the forwardConfig, which was not clear before due to lack of indentation.

Issue

General improvement for docs readability, not related to an issue

Description

When configuring the forwardConfig, it was not initially clear to me that these two properties were part of the forwardConfig block since they were indented to the same level as it, instead of indented a layer deeper to show nesting.

This change simply provides the extra indention in the example code of the docs which should make it clearer to other readers to prevent them from making the same mistake.

Hi @jacurtis. 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.
