Route enable-internal-sources by Agent.Os at runtime and use SetupNugetSources.sh on Unix

[Copilot]

enable-internal-sources.yml was invoking SetupNugetSources.ps1 on Unix via pwsh, which pulls in tools.ps1 and Windows-centric behavior. This change switches Unix execution to SetupNugetSources.sh and updates OS routing to use runtime task conditions.

• Template routing by platform

  • eng/common/core-templates/steps/enable-internal-sources.yml now routes by Agent.Os at task runtime using condition:.
    • Windows: PowerShell@2 + SetupNugetSources.ps1
    • Unix: Bash@3 + SetupNugetSources.sh
  • Applied consistently for legacy credential and federated-token flows.
  • Avoids relying on Agent.Os during template expansion.

• PowerShell invocation alignment

  • Template calls pass -Password to SetupNugetSources.ps1 (no script parameter alias changes required).

• Scope after review feedback

  • Reverted prior changes to eng/common/SetupNugetSources.sh credential-update behavior.
  • Reverted prior SetupNugetSources.ps1 parameter alias change.
  • Reverted the added credential-update regression test tied to the reverted shell behavior.

- task: PowerShell@2
  condition: and(succeeded(), eq(variables['Agent.Os'], 'Windows_NT'))
  inputs:
    filePath: $(System.DefaultWorkingDirectory)/eng/common/SetupNugetSources.ps1
    arguments: -ConfigFile $(System.DefaultWorkingDirectory)/NuGet.config******
- task: Bash@3
  condition: and(succeeded(), ne(variables['Agent.Os'], 'Windows_NT'))
  inputs:
    filePath: $(System.DefaultWorkingDirectory)/eng/common/SetupNugetSources.sh
    arguments: $(System.DefaultWorkingDirectory)/NuGet.config $Token

To double check:

• The right tests are in and the right validation has happened. Guidance: https://github.com/dotnet/arcade/blob/main/Documentation/Validation.md

Pull request overview

This PR updates the enable-internal-sources.yml pipeline template to select the feed-setup implementation at task runtime based on Agent.Os, ensuring Unix agents run the Unix-native SetupNugetSources.sh instead of invoking the PowerShell script via pwsh.

Changes:

• Route internal-feed setup tasks by Agent.Os using task condition: (Windows uses PowerShell@2, non-Windows uses Bash@3).
• Switch Unix execution to eng/common/SetupNugetSources.sh for both legacy credential and federated-token flows.
