Wrong link in the documentation (ConvBERT, BART, Fnet)
In the documentation on transform-based models [0], the link that is supposed to point to the **ConvBERT** paper [1, 2] points instead to the **DistilBERT** paper [3].

[0] https://huggingface.co/docs/transformers
[1] https://huggingface.co/docs/transformers/model_summary#convbert
[2] https://arxiv.org/pdf/2008.02496.pdf
[3] https://arxiv.org/pdf/1910.01108.pdf
Nice catch! Would you like to submit a PR to amend this?<|||||>Sure ! As soon as I finish reading the documentation, to avoid making two PRs in case I find another error.<|||||>Going through the documentation I found an error and a warning. I'll make a PR about it. I just want to note that I didn't do a documentation review, I stumbled upon these errors by coincidence: my remarks should therefore not be considered an absolute documentation review.

# Fnet [1]
At the level of model documentation, the label corresponding to FNet is rather FlauBERT (see screenshot below)

# BART [2]
At the level of the model documentation, the link that points to the BART authors' code points to a github branch that has been modified [3, 4].
