docs: fix simple typos

[lpmi-13]

Description of the change:

Fixes two simple typos in the comments of the Dockerfiles.

Motivation for the change:

I noticed in my generated Dockerfile after calling operator-sdk create-api that there were a couple simple typos, and the only place I could find that string was in these files. I'm unsure whether this will also impact the generated Dockerfiles for the project, but if that's also in this repo somewhere, I would happily add that change to this PR as well.

Hi @lpmi-13 These files actually come from kubebuilder you'd need to raise a PR to that repo to fix this at the source, since this would get overwritten at testing/generation time.

I believe the below is the source.

Much obliged, I'll raise something there instead 🫡
