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=1.669e-06; Maximum crossload hidden layer difference=1.544e-01;
Maximum conversion output difference=1.669e-06; Maximum conversion hidden layer difference=1.544e-01;


CAUTION: The maximum admissible error was manually increased to 0.2!
