Update chart dependencies

Update dependencies of all charts

@groundhog2k would you be opposed to installing Renovate on the repo? We're using it with great success in my org to automate dependency updates.

I know renovate and we are using it to update different projects (NodeJS, Java, K8s deployments etc.). But how can it update the Chart.yaml (appVersion/version, charts dependencies)? To my knowledge renovate isn't able to do that, but maybe I'm wrong. To update an appVersion in a Chart.yaml it must be aware of the latest Container image version in the container registry (docker.ui or others). I don't think renovate can do that. As far as I know, it is able to update Dockerfiles, K8s manifests, maybe values.yaml, but not helms Chart.yaml.
Do you know a solution?

From the Renovate Helm chart of it updating its own image renovatebot/helm-charts#3067 looks like they have a custom manager for handling all of the places that it's used in their docs.

https://github.com/renovatebot/helm-charts/blob/7bdbd4574ec9704ebf95571379a2b66b2228793c/renovate.json#L10-L29

Would want some tests before I'd feel comfortable enabling auto-merging without approval, but it removes the step of tracking when releases are made. Plus something like release-please and the repos tick over by themselves until there's a breaking change.

It is an official Renovate feature. For more information about projects using it, take a look at the feedback thread.
