Use Nuget.Config file in migrations bundle command

Dear,

I'm trying to use the "dotnet.exe ef migrations bundle" command with a nuget.config file defined on the sln folder level, but I don't see any parameters where I can define the path or the service connection name to use to authenticate against the external feed defined in the nuget.config. I'm trying this in azure pipelines, and external feed is in Nexus.

Steps in the pipeline:

* checkout
* install ef tooling
* use SDK (7.x)
* restore by use of nuget.config and externalFeedCredentials
* dotnet build of the sln with no-restore
* Nuget Authenticate
* dotnet core cli task with custom ef migrations bundle command

```
- task: DotNetCoreCLI@2
inputs:
command: 'custom'
custom: 'ef'
arguments: 'migrations bundle --configuration bundle -s "$(System.DefaultWorkingDirectory)/repo/${{parameters.workingDirectory}}/${{parameters.migrationsProject}}" -f --output "$(Build.ArtifactStagingDirectory)/migrations/efbundle_main.exe" --verbose'
```

the error:

starts when ef is building the bundle:

```

```

I would expect it to try and get those custom packages out of the nexus feed as that is defined in the nuget.config.

The dotnet restore and dotnet build tasks are running ok, but with the restore task I can give along the nuget.config path and the service connection it needs to use.

tried it also with --no-build but then the configuration bundle seems to try and get the packages in the debug configuration folder, while the dotnet build of the sln is in the release configuration.
