[BUG] Unrecognized option '--skip-duplicate'

[TheBeachMaster]

Describe the bug
This is somewhat similar to #37 .

Given that #37 was closed with a link to #4864 and commit c12b854

I have still encountered this issue trying to publish to Nuget with the following error

Generated Package(s): AfricasTalking.NET.1.2.1.nupkg
executing: [dotnet nuget push *.nupkg -s https://api.nuget.org/v3/index.json -k *** --skip-duplicate -n 1]
Specify --help for a list of available options and commands.
error: Unrecognized option '--skip-duplicate
