🐛 handle broken backslash path bug on windows

[Shuliyey]

change

• change backslash \ to / on new_path function

Background

walrus-site can't render \ url as browser (e.g chrome) auto convert url path \ to /, on windows site-builder will upload object as \ when interacting with walrus-sites move contract, therefore the object path will be inserted as \

Solution

replace \ with / in object path, before writing object to Walrus
