Support nuspec manifest download for nuget packages (#28921)
Support downloading nuget nuspec manifest[^1]. This is useful for renovate because it uses this api to find the corresponding repository - Store nuspec along with nupkg on upload - allow downloading nuspec - add doctor command to add missing nuspec files [^1]: https://learn.microsoft.com/en-us/nuget/api/package-base-address-resource#download-package-manifest-nuspec --------- Co-authored-by: KN4CK3R <admin@oldschoolhack.me>
