Allow to set environment variables for build tasks?

[michaelsauter]

I'm wondering if we should allow to set environment variables in the build task containers via the Helm chart, in the same way we allow to control the sidecars / resources. This could be used to set env vars needed for testing for example, however often there are other ways of doing this as well so not sure if we really need it.

I'm going to close this. There hasn't been a concrete use case so far, and the general direction would be to try to use central tasks (e.g. from Artefact Hub, see #620) instead of tasks defined in the Helm chart.
