`TemplateVerificationException.TemplateVerificationErrorCode` does not seem to be set correctly

dotnet CLI (dotnet new)

Describe The Bug

I was adding some tests for a template and fat-fingered some of the TemplateVerifierOptions in the process. I noticed the TemplateVerificationException.TemplateVerificationErrorCode does not match the error code reported in the exception message itself nor in the console output which is sent to the ILogger.

The docs for the enum specify that these should correspond to the dotnet new exit codes.

To Reproduce

1. Create a folder containing a basic template - The template itself and its content is not important in this scenario. It just needs to exist and overall be valid (for one of the error cases)
2. Create a new xunit project to test the template
3. Add the Microsoft.TemplateEngine.Authoring.TemplateVerifier nuget package
4. Add a test for an "Invalid template path" scenario:
   • Set TemplateVerifierOptions.TemplatePath to a non-existent path
   • Assert that the VerificationEngine.ExecuteAsync(options) throws a TemplateVerificationException
   • Assert that the exceptions TemplateVerificationErrorCode is InstallFailed (106)
5. Add a test for an "Invalid template name" scenario:
   • Set the TemplateVerifierOptions.TemplatePath to point to the template folder from step 1
   • Set the TemplateVerifierOptions.TemplateName to a non-existent name
   • Assert that the VerificationEngine.ExecuteAsync(options) throws a TemplateVerificationException
   • Assert that the exceptions TemplateVerificationErrorCode is TemplateDoesNotExist (103)
6. Run dotnet test:
   • Observe that both tests fail because, in both cases, the ErrorCode is set to InstantiationFailed
   • Observe that the exception Message include the error code 106 and 103 respectively.
   • Observe that the console output reported to the ILogger also mention the 106 and 103 error codes.
