fix: revert hashstructure to v0.6.0 to keep artifact IDs stable (#5364)

* fix: revert hashstructure to v0.6.0 to keep artifact IDs stable

hashstructure v1 changed `SlicesAsSets` hashing (every slice now gets a finalizing hash pass, and duplicate elements are deduplicated), which changed nearly every artifact ID syft produces.

- pin `github.com/gohugoio/hashstructure` back to v0.6.0 and have dependabot ignore major bumps
- make the aggregate `Unit tests` job fail when a dependency fails; previously it was skipped, which satisfies the required check and let #5277 auto-merge with failing unit tests

* ci: fail unit test gate on any failed, cancelled, or skipped dependency

* ci: require every unit test dependency to succeed
