Adding datasets related to this model

Hi!

I'm testing the evaluation on the Hub feature.

In particular, I'd like to evaluate this model with out-of-domain data, and specifically a small dataset I've just labelled containing recent tweets about wildfires and climate change.

For context, to use the evaluation feature related datasets must be listed in the model card: https://huggingface.co/spaces/autoevaluate/model-evaluator/discussions/11

Thanks for considering adding this! I'm a big fan of all the models you are releasing at CardiffNLP
