"*-controller-manager" typo fix

[bridgetkromhout]

I noticed a typo in a recent blog post, and a similar typo appears in
the comments for some examples. This PR corrects these typos.

I see https://kubernetes.io/docs/contribute/new-content/overview/#languages-per-pr but I'm not sure if it applies since I'm changing English-language comments. If this needs to be PRed separately regardless of not needing language-specific review, please let me know. Thanks!

I hope this isn't too much of a merge problem for other localizations (the concern with languages per PR is mainly about the work for localization teams to manually resolve conflicts on their WIP branches)
