GridAnimation3D write should have a show argument

The problem seems to be that for example within a Jupyter notebook, showing the 3D plot somehow closes the video file or something.
This can be solved by not showing the plots, but that should be an option anyway!

Like this:

    def write(self, filename, framerate=24, show=False):
        """
        Write the animation to a video or gif.

        Resets the plotter when finished animating.

        Parameters
        ----------
        filename : str, pathlib.Path
            Filename to write the video to. Should be an .mp4 or .gif.
        framerate : int, optional
            Frames per second. Not honoured for gif.
        """
        if Path(filename).suffix.lower() == ".gif":
            self.plotter.open_gif(
                Path(filename).with_suffix(".gif").as_posix()
            )  # only lowercase gif and no Path allowed
        else:
            self.plotter.open_movie(filename, framerate=framerate)
        if show:
            self.plotter.show(auto_close=False, interactive=False)

Start by locating the GridAnimation3D.write entry point and inspect how its plotter is shown while writing a video or GIF. Add the requested show option so notebook users can choose whether to display the plot, then verify both video-writing behavior and the no-show case in a Jupyter notebook.
