Metadata and other non-component files are counted in RHC percentage identified for npm repositories

1. Start up Nexus Repo 3.22.1
2. Add an npm proxy repository with remote of https://registry.npmjs.org
3. Request a package's metadata through it: http://localhost:8081/repository/npm-proxy/lodash
4. Request a package from that metadata: http://localhost:8081/repository/npm-proxy/lodash/-/lodash-4.17.9.tgz

Observe that the generated health check report shows 25% of components identified (screenshot attached).

Analysis shows that the package metadata and other non-component files are being included in the percentage identified.

The percentage identified is therefore misleading. 100% of components in the repository are identified, but the report always shows a much lower percentage.
