to deploy the model by pushing it to replicate

[emirhanbilgic]

Some changes have been made for users who want to deploy the trainable model by pushing it to replicate.com.

If these changes are not made, the following error is encountered:

Error no file named pytorch_model.bin, tf_model.h5, model.ckpt.index or flax_model.msgpack found in directory ./sdxl-cache.
https://replicate.com/p/qy7ge2tb2mwwc7guoi7mztttpe?input=form

For this reason, the download_weights.py script should be unextended and can be run with cog run ..., also ./sdxl-cache should be removed from dockerignore.
