Comparison Chart (Table) for all the existing BERT models.
# 🚀 Feature request

Can we have a Comparison Chart (Table) for all the existing BERT models in one place. 
For an example:

- Data the model is trained on?
- Hidden layers?
- Architecture difference?
- How it can be loaded for classification/generation - 2-3 lines of Code ?
- Does it has pooler layer or not?
- Parameters
- Model Size
- General Inference time 
- Training time


The chart table then will have link to deep-dive in details directed to the model page.


## Motivation

Sometimes it becomes overwhelming to go through each of the models ( too many of them). If its in a comparison chart then it becomes very simplified.


It's just an idea. We can elaborate or work on this idea.
