text: Title: file_dropper extension not loaded, but no file_dropper extension after adding
  Body: ```python
  
  2024-08-15 15:43:37,814 pn.extension was initialized but 'file_dropper' extension was not loaded. In order for the required resources to be initialized ensure the extension is loaded with the following argument(s):
  
  pn.extension('file_dropper')
  ```
  
  The correct one is `filedropper`, but I think this message is auto formatted somewhere
