dotnet workload search version shows duplicates if multiple copies found from different feeds #50979
Description
Describe the bug
We only publish the final version to nuget.org but we have workload sets available in other feeds for testing. When a customer runs dotnet workload search version, we should make sure the output is distinct. Generally, these workload sets should have identical contents so it shouldn't matter which feed we ultimately pull from for other actions (like details or install).
To Reproduce
Install RC1
Create a nuget.config file
Add nuget.org and the dotnet10-workloads feed
dotnet workload search version
