I had to remove the Copied from to address https://github.com/huggingface/transformers/pull/20550/files#r1039877563 / let's keep this in mind

Still some problems with the inconsistent checkpoint names, and the model type for ViTHybridConfig. Also make sure the actual more repos are in the right places on the Hub.
| This is the configuration class to store the configuration of a [`BitModel`]. It is used to instantiate an BiT | ||

Needs to be updated to google/bit-50

Same, checkpoint needs to be the vit-hybrid one.

What does this PR do?
This PR adds ViT hybrid to the library. As ViT hybrid uses BiT as backbone, this PR also adds BiT as a standalone model.
BiT itself is very similar to a ResNetv2, except that it replaces batch norm layers by group norm and uses "weight standardized" convolutional layers.
To do:
