SwinUNETR requires 'img_size' argument, then refuses to use it because it is deprecated

[louisfabrice13]

Describe the bug
SwinUNETR requires 'img_size' argument, then refuses to use it because it is deprecated

To Reproduce
Define a SwinUNETR model with 'img_size' argument, and without it.

Expected behavior
I would expect at most a deprecation warning, without the model breaking if img_size is indeed input, and a smooth instantiation without img_size.
