Add scenario test for globalization

[lbussell]

Currently we have the following test that is ran inside the SDK images when testing xunit functionality:

dotnet-docker/tests/Microsoft.DotNet.Docker.Tests/TestAppArtifacts/UnitTests.cs

Lines 12 to 19 in 4f48d36

	/// <summary>
	/// This ensures that localization is properly configured in the sdk image.
	/// </summary>
	/// <remarks>
	/// See https://github.com/dotnet/dotnet-docker/issues/3844
	/// </remarks>
	[Fact]
	public void CurrencyLocalization()

This is not sufficient to validate Globalization functionality in all images. We should add a test that validates all aspects of globalization are working correctly:

• The test should detect if globalization is enabled in .NET.
  • If globalization is enabled:
    • It should validate that the environment variable is set.
    • It should validate that localization works (currency formatting for example).
    • It should validate that using time zone related classes works.
  • If globalization is disabled:
    • It should validate that calling globalization-related methods fails.
