Get NuGet package versions from federated PURL version data in https://github.com/aboutcode-data/

[keshav-space]

Fetchcode returns no version for pkg:nuget/Microsoft.WindowsDesktop.App.Runtime.win-arm64, but we have all the versions for this package in https://github.com/aboutcode-data/purls-nuget-0128/blob/main/nuget-0182/Microsoft.WindowsDesktop.App.Runtime.win-arm64/purls.yml.

In [13]: from fetchcode.package_versions import versions

In [14]: list(versions("pkg:nuget/Microsoft.WindowsDesktop.App.Runtime.win-arm64"))
Out[14]: []

This issue impacts our ability to unfurl NuGet versions and flag ghost NuGet packages.
