Feature parity with dynamic prompts: wildcard directory setting

[demoran23]

I noticed at https://civitai.com/models/45448?modelVersionId=164799 they recommended to switch to this extension, but my wildcards are located in a shared location. This extension can't find them.

The solution is to move them to the Umi Wildcards directory. Though. I'm kinda (trying) to work on Umi 2.0. It's a bit of a process.

@demoran23 one solution is to move them, another is to tell us what is that shared directory relative to the extensions directory. We can scan other ones than the extension one but up to this point there was no need for it.
