Hi, I really appreciate the Huggingface and the fantastic code for pretrained LMs.
I am trying to figure out the date of Wikipedia dumps used for pretrained checkpoints. (BERT and RoBERTa)

## Details
<!-- Description of your issue -->
I'd like to know the date (month, year) of Wikipedia dumps that were used for the current pretrained checkpoints of BERT-base uncased and RoBERTa-base and large.
I am looking for an older version of pretrained checkpoints that were trained on a Wikipedia dump before 2019.
If available, is there a way to get the older version of pretrained checkpoints (before 2019)?
Thanks!
