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=1.502e-05; Maximum crossload hidden layer difference=6.371e-04;
Maximum conversion output difference=1.502e-05; Maximum conversion hidden layer difference=6.371e-04;
