📖 Add kubebuilder FAQ section

[astraw99]

Fixes #1318 #1723 #3016 #3028

Add a FAQ section in the KB docs, and include some of the representational reported issues.
Will update it continuously, to help more users.

Also add git-repo and git-edit icons on the top-right page.
Tested with mdbook serve locally, works fine.

Hi @astraw99. 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.

This one is only to add a new FAQ section on the docs with some questions/answers.
It seems fine to be get merged without a second review.

Anyway we can always do follow up PRs to improve this one.
