Update SpecAssay bundle to v0.5.6 (#4855)

Update specassay submitted by @rdryfoos in the community catalog and documentation. The release metadata, pinned artifact URL, and downloaded archive digest now reflect v0.5.6. Validation confirmed the public repository manifest, README, license, documentation, release asset, component catalogs, checked submission requirements, and archive checksum. Closes #4852
