Describe the bug

As seen here: https://github.com/jonathanpeppers/inclusive-code-reviews-ml/pull/29#discussion_r944879120

A pipeline such as:

            var dataProcessPipeline = mlContext.Transforms.Conversion.MapValueToKey("isnegative", "isnegative")
                                      .Append(mlContext.Transforms.Text.FeaturizeText("text_tf", new TextFeaturizingEstimator.Options
                                      {
                                          //NOTE: not exportable to ONNX
                                          KeepNumbers = false,
                                          KeepPunctuations = false,
                                          // NOTE: these work
                                          KeepDiacritics = true,
                                          CaseMode = TextNormalizingEstimator.CaseMode.Lower,
                                      }, "text"))

Hits an exception such as:

To Reproduce

Steps to reproduce the behavior:

Run this project:

https://github.com/jonathanpeppers/inclusive-code-reviews-ml/tree/main/ml.net/InclusiveCodeReviews.Convert

Uncomment these two lines:

https://github.com/jonathanpeppers/inclusive-code-reviews-ml/blob/486f7737174702233825ceddf28adb5cc7912f43/ml.net/InclusiveCodeReviews.ConsoleApp/ModelBuilder.cs#L59-L61

Expected behavior

In particular, we want to use KeepPunctuations=false and export to ONNX.
