OK, we identified the source of this problem. Turns out that the Github Action we use for auto-generating our docs site is overwriting the Git commits in the gh-pages branch.

We were storing our Helm Charts in the charts/ directory of the gh-pages branch and unfortunately the last commit that modified the docs/ content overwrote our Charts. :(

So, I need to regenerate the charts and push them. However, we have decided that since we still have not published our updated install docs that refer to the gh-pages Helm Charts repository, we are going to instead publish to a new ECR Public repository and use ECR instead of Dockerhub for storing the binary ACK service controller images.

Please see #461 for information on what we need to do here. I'm going to close this bug out in favor of #461
