fix: fix missing version/namespace in maven & npm

[zvigrinberg]

Description

Main component in SBOM being generated is sometimes missing namespace Or version, it happens only for maven and npm component analysis:

1. in maven, it happens because of existence of parent pom, and pom.xml not specifying the groupId ( mapped to namespace in sbom' purl) or version, and then effectively inherits them from parent.
2. in npm, if package.json doesn't specify version, then it happens, and in npm, the package name can be comprised from namespace/package, or only package, in the latter case, namespace Will be not populated in purl of npm, and it's ok as it's not mandatory for npm.

fixes JIRA APPENG-2318
