@pmalek I changed the kong/kong repository from https:// to file:// deliberately to allow bumping both charts in a single commit. Is this something that we'd like to avoid? As I understand, we always want to make them be in sync - that enables us to make it happen without an additional PR to bump kong/ingress dependencies separately.

I do recall there was a discussion about this at some point. Perhaps @programmer04 or @rainest can chip in. I believe one of the arguments against it was that we wouldn't explicitly know which version are we using at particular point in time (it would be the current version during the helm dependency update invocation). Now we don't have that solve either, we only have the minimal version and we rebuild the deps on release (this is similar to what you proposed in this PR).

I'm not sure what would be the best approach for this 🤔

👍 Alright, to not block this PR on this, I backed off to only kong/kong changes and will proceed with a separate PR bumping this in kong/ingress.
