[Bug]: Extension doesn't support symlink?

[R-N]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What happened?

Webui raises errors when loading extension files when extensions folder is sylinked. It also won't install extension from webui (can still git clone manually).

Steps to reproduce the problem

1. Clone webui
2. Delete extensions folder
3. Symlink extensions folder from somewhere else
4. Clone extensions there
5. Run webui
6. Open webui. Will raise errors
7. Install an extension. Will raise error

What should have happened?

Extensions are loaded and installed normally

I'm testing this myself but this should fix it. https://github.com/AUTOMATIC1111/stable-diffusion-webui/pull/4684
