Feature: Consider swapping Goja with Sobek

### Feature description

The grafana/k6 team forked Goja because, among other reasons, their PR to add ES Modules support to Goja sat in limbo for far too long.

They clearly have much more resources and motivation than Goja's dev, so it seems that Sobek is the way forward for JS in Go. K6 is already using it in their quite mature and demanding Production environment. It would be great if Conduit could leverage it!
