Set additional properties when generating sbom for nugets

When generating a SBOM the below properties should be set to provide a richer experience & better information.
- **Group** the first segment of the package name
- **publisher** is the owner as specified in Nuget (nuspecmodel), if empty use author
- **releasenotes** as specified in Nuget (nuspecmodel)
- **properties** with a property for the language of the package
- **properties** with a property for the tags of the package
- ~~**supplier** the url/name of the repository used to source package. This would need to come from package source mapping.~~ will be handled via #845

Locate the NuGet SBOM generation entry point and inspect how nuspecmodel data is mapped to components. Done means setting group, publisher with the author fallback, release notes, and package language and tag properties, while leaving supplier for issue #845.
