Python #| fig-cap: produces <p> tags not <figcaption>

It might be worth taking a fix for this for 1.4, and make the jupyter behavior equivalent to that of knitr.

Description

```{python}
#| echo: false
#| fig-cap: "This is my figure caption"

fig =  makeplotlyfig() #some function that makes a plotly figure
fig.show()
```

So, the above code in Quarto 1.4x, there is a caption underneath the plotly figure but it is wrapped in <p> tags and looks exactly like the rest of the text. By contrast, a Figure caption added to an inline image ala ![Elephant](elephant.png) the caption is wrapped in <figcaption>.

I think this is bug? EDITED to say that this is Quarto version 1.4.532
