dotnet tool install doesn't respect packageSourceMapping

### Describe the bug
dotnet tool install doesn't respect packageSourceMapping in nuget.config

### To Reproduce

Given this nuget.config

```xml

```

When I try to run the following command:

```sh
dotnet tool install swashbuckle.aspnetcore.cli
```

Then I expect that only the `nuget.org` feed to be used
