Add sample testing to nightly test automation in devfile registry

Issue Description

The current nightly test run in the devfile registry only test for the stacks but there is no sample coverage. We need to add the sample tests to the nightly to catch any problems related to the samples due to change in the starter projects.

This might have some overlap with #1142, I'd say we should preserve this one.

devfile/registry#195 covers part of this though there is still some additional coverage needed, e.g. testing on starter projects.

We might need to define acceptance criteria for the issue. I'm putting it on waiting for now.

#1142 may become a blocker for this issue.

Putting item back in refinement as I cannot see why is in the waiting status
