feat(storage)!: update file by url endpoints

[ChrisPdgn]

All "move" and "rename" provider functions are removed as most providers don't support a move operation.
With that stated, the updateFile endpoints now require the file data too, either by passing it as a body param or by uploading the file by url
Fix: Add checks in places where filename is given, in case folder name is '/'
