Add model-last saving mechanism to pretraining (#12459)
* Adjust pretrain command * chane naming and add finally block * Add unit test * Add unit test assertions * Update spacy/training/pretrain.py Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com> * change finally block * Add to docs * Update website/docs/usage/embeddings-transformers.mdx * Add flag to skip saving model-last --------- Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com>
