[Suggestion] Glue Diagnostic Data with Labels 
Hello! First of all, thanks for setting up this useful project!

I've just realised you provide the the [Glue Diagnostics Data](https://huggingface.co/nlp/viewer/?dataset=glue&config=ax) without labels, indicating in the `GlueConfig` that you've only a test set.

Yet, the data with labels is available, too (see also [here](https://gluebenchmark.com/diagnostics#introduction)):

Have you considered incorporating it?
