nugetclean allows to unlist pre-release versions of a nuget package once a new
version is released.

dotnet tool install --global SIL.NuGetCleanernugetclean --api-key=<nuget api key> [--dry-run] <packageid>--api-key - the NuGet API key with the permission to unlist a package
--dry-run - only list the package version that would be unlisted, but don't do it
<packageid> is the NuGet package id.
