Generate SBOMs for JS components

[toddbaert]

We have SBOMs currently for Java and Go contribs. We could use them here as well. I recommend this utility: https://github.com/marketplace/actions/cyclonedx-node-js-generate-sbom (we're using the clyclonedx format elsewhere and it's popular).

Definition of done:

• SBOMs generated and attached to release artifact in GH, or otherwise made publicly available (for every release)
• runtime dependencies only included
• only includes dependencies of module in question (not of repo)
