[Enhancement]Use scripts.basedir() than prompt_gallery_name.json

Use scripts.basedir() than prompt_gallery_name.json
I think it's simpler, don't you?

No it points to the rootpath of webui

>scripts.basedir()

No, you shoud not use it in function.
But like this:

extension_dir = scripts.basedir()

def on_app_started(demo: Optional[gr.Blocks], app: FastAPI):
    app.mount('/prompt_gallery', StaticFiles(directory=extension_dir,html=True))
