[BUG] The suggestion in `examples/notebook_workflow.ipynb` don't match the suggestions printed by `render.py`

[IgorTatarnikov]

The example in notebook_workflow.ipynb has the below as instructions for displaying the scene:

# To display the scene we use `vedo`'s `show` method to show the scene's actors
from vedo import Plotter  # <- this will be used to render an embedded scene 
plt = Plotter()
plt.show(*scene.renderables)  # same as vedo.show(*scene.renderables)

Meanwhile the text printed below the cell (from render.py) suggestions something different.

brainrender/brainrender/render.py

Lines 272 to 280 in f006213

	elif self.backend == "k3d": # pragma: no cover
	# Remove silhouettes
	self.remove(*self.get_actors(br_class="silhouette"))
	print(
	f"[{teal}]Your scene is ready for rendering, use:\n",
	Syntax("from vedo import show", lexer="python"),
	Syntax("vedo.show(*scene.renderables)", lexer="python"),
	sep="\n",
	)

Running this results in an incorrect output:

The text should be harmonised and we should pick one way of suggesting users run brainrender in a Jupyter notebook.

Hi, I'd like to work on this. I'll harmonize the notebook example and the render.py suggestion to use the same approach.
