Add TF weights

Model converted by the [`transformers`' `pt_to_tf` CLI](https://github.com/huggingface/transformers/blob/main/src/transformers/commands/pt_to_tf.py). All converted model outputs and hidden layers were validated against its PyTorch counterpart.

Maximum crossload output difference=2.629e-07; Maximum crossload hidden layer difference=3.934e-05;
Maximum conversion output difference=2.629e-07; Maximum conversion hidden layer difference=3.934e-05;
