/lgtm

Both bash build-tools/cache_samples.sh tests/registry/extraDevfileEntries.yaml .cache/samples and STACKS_DIR=tests/registry/stacks bash build-tools/dl_starter_projects.sh produced expected results.

Usually yq gives me a headache on Mac but it ran smoothly, I think the bump to the version fixed some issues or something!
