SBOM tool always includes package entry when .nuspec file is found

[jalkire]

The underlying component detector for nuget packages includes, among other things, *.nuspec files. This means that if a .nuspec file is present during SBOM generation, the package that it defines will be included in the packages section of the SBOM. This will happen regardless of if that package is actually installed/present, and can lead to misleading results. CD acknowledges this potential in their docs.
