[Bug] Use raw dir name to serve static web content

Resolves https://github.com/Comfy-Org/manager-core/issues/9

The urllib.parse.quote(name) was added in

9b1d5a5#diff-791d4d41d3718d15d49180f3aacc8370b8cab07383f0d35b2713651cc0adfe46R511

However, it is causing issue if there are special characters in the custom node directory, such as @. Previously the issue was not surfaced as github repo name cannot contain any special character that urlencode to something else, until the repo@version syntax was introduced by the manager.

Step to reproduce

• Install ComfyUI
• Install ComfyUI-Manager
• switch ComfyUI-Manager to feat/cnr branch (https://github.com/ltdrdata/ComfyUI-Manager/tree/feat/cnr)
• Install a custom node that contains frontend modules via the manager (e.g. ComfyUI-easy-use)
• Observe 404 in the console after restart

Discussed with HCL offline. This should not cause any regressions because github does not allow special characters in their repository name anyways. So this was probably never needed in the first place.

Tested and works for me.
