Support for private docker registry

[prabhu]

Testing private docker registry

git clone https://github.com/CycloneDX/cdxgen
cd cdxgen
git checkout feature/nov23-updates
npm install
# docker login
node bin/cdxgen.js ...

Test scenarios

• All unauthenticated journeys should work as-is
• Default DOCKER_CONFIG. Performing docker login followed by cdxgen invocation should correctly generate the sbom.
• Override DOCKER_CONFIG with environment variables
• Test by specifying DOCKER_AUTH_CONFIG and other individual environment variables
• Test with a credential helper and credential store such as docker desktop
• Manually pull the image and then invoke cdxgen.

Known issues

• http: server gave HTTP response to HTTPS client - Set the insecure registries in daemon.json

Ignore the Codacy findings, which are unproductive (They are running the same eslint with slightly different settings and get it wrong 100% of the time).

From initial testing, it appears like the bug with the private docker registry is still not resolved. However, the package updates specifically the update to the atom package are required for improving reachable components detection for the depscan v5 release.

Will create a new PR with only the package updates and another one specifically for the private docker registry. - DONE
