fig-height/fig-width with Pyodide might not be respected in RevealJS

[coatless]

Not sure that fig-height/fig-width cell options are being applied in a pyodide cell. If I'm remembering, the underlying matplotlib integration is using a custom shim?

## Let's graph

```{pyodide}
#| fig-height: 3
#| fig-width: 3
#| echo: false
#| autorun: true
import numpy as np
import matplotlib.pyplot as plt

a = 1
b = 0

x = np.linspace(0, 10, 100)
y = a * x + b

plt.figure(figsize=(8, 4))
plt.plot(x, y)
plt.grid(True)
plt.title(f'Linear Function: y = {a}x + {b}')
plt.show()
```
