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-05; Maximum crossload hidden layer difference=9.766e-03;
Maximum conversion output difference=1.669e-05; Maximum conversion hidden layer difference=9.766e-03;


CAUTION: The maximum admissible error was manually increased to 0.1!

See [GitHub PR #25558](https://github.com/huggingface/transformers/pull/25558) for details, precision overridden due to hidden states being a little weird in TF; final output logits are within 1.788e-05 for all model variants/sizes.
