docs: Registers a single Comet callback function
          (see :ref:`comet-plugin`).
  
          Refer to :func:`sijax.plugin.comet.register_comet_callback`
          for more details - its signature differs slightly.
  
          This method's signature is the same, except that the first
          argument that :func:`sijax.plugin.comet.register_comet_callback`
          expects is the Sijax instance, and this method
          does that automatically, so you don't have to do it.
