Harden dynamic / submit-nuget by making dependency submission non-blocking

[Copilot]

dynamic / submit-nuget (dynamic) failed due to an HTTP error in the GitHub dependency-submission action (actions/component-detection-dependency-submission-action), not from NuGet packaging logic. This change prevents external dependency graph submission outages/permission mismatches from failing the job.

• Workflow reliability

  • Updated the dependency-submission step in the dynamic NuGet workflow to avoid failing the entire job when the submission action returns a non-retryable API error.
  • Kept the step present so dependency data is still submitted when permissions and API availability are healthy.

• Failure isolation

  • Scoped the mitigation to the dependency-submission path only; package generation/publish flow remains strict and unchanged.
  • Preserved existing execution order and conditions for the submit-nuget workflow.
