Embed for a Jupyter Percent script

Quarto supports now expressing notebook as Jupyter percent script and will render it using usual Jupyter engine pipeline

import matplotlib.pyplot as plt           
import seaborn as sns

g = sns.FacetGrid(df, hue="species", height=3, aspect=3.5/1.5)
g.map(plt.scatter, "bill_length_mm", "bill_depth_mm").add_legend()

Howerver for now, this is seen as unsupported embed

ERROR: Unable to embed content from script.py - embedding content is not supported for this file type.

Maybe it would be ok to support this ?

Following discussion in https://github.com/quarto-dev/quarto-cli/issues/10366#issuecomment-2252163412

Start with src/core/jupyter/jupyter-embed.ts and the embed handling paths in src/core/handlers/embed.ts and src/core/handlers/base.ts, using the reported unsupportedEmbed stack trace as the entry point. Verify the behavior with the issue's script.py#fig-bill-sizes example; done means that embed syntax can resolve a figure from a Jupyter percent script through the usual Jupyter pipeline.
