What happened?

When installing an extension inside a Docker container, I now get this error:

Error completing request
Arguments: ('https://github.com/d8ahazard/sd_dreambooth_extension', ['ads', 'localization']) {}
Traceback (most recent call last):
  File "/home/stable/stable-diffusion-webui/modules/ui.py", line 185, in f
    res = list(func(*args, **kwargs))
  File "/home/stable/stable-diffusion-webui/modules/ui_extensions.py", line 144, in install_extension_from_index
    ext_table, message = install_extension_from_url(None, url)
  File "/home/stable/stable-diffusion-webui/modules/ui_extensions.py", line 135, in install_extension_from_url
    os.rename(tmpdir, target_dir)
OSError: [Errno 18] Invalid cross-device link: '/home/stable/stable-diffusion-webui/tmp/sd_dreambooth_extension' -> '/home/stable/stable-diffusion-webui/extensions/sd_dreambooth_extension'

Steps to reproduce the problem

Run AUTOMATIC1111 from a Docker container with extensions mounted during docker run, try to install an extension.

What should have happened?

The extension should have installed.

Additional information, context and logs

I believe the answer may be as simple as using shutil.move instead of os.rename
