I also need #1109 merged so I can rebase

Let's wait here until we decide at which commit we branch

We still have the weird Helm dependency on the latest tagged image that messes up the release guide a bit. I'm working on an outline to address that, but for this release here's what I propose:

1. We finish all code merges for v0.27
2. Tag v0.27
3. Merge this PR (so we get an automatic build that's tagged with v0.27)
4. Promote the v0.27 image upstream
5. Finish the release process with Helm chart updates

Basically since this is just a docs change, we use that as the trigger post-tag to unblock the Helm chart updates. Does that sound good?

Sounds good! I'll try to document this for next release project (if not made already)

Awesome, thanks! Merging this so we can get a build for v0.27. Then we just need the image promotion, and that will unblock the Helm PRs
