Fix versioned metrics

I hope that another side-effect of building without optimization (sorry I forgot this) is that cabal can use use caches from the ubuntu20-builder builder now, which also builds without optimization.

Don't we need to build images that are production ready, with optimizations? Those charts/images we release should have optimizations enabled, no?
For CI I agree it doesn't matter, but perhaps in some refactoring this was turned off at some point?
