revealjs speaker view lightbox activation doesn't propagate to presentation view

[d-morrison]

I have:

• searched the issue tracker for similar issues
• installed the latest version of Quarto CLI
• formatted my issue following the Bug Reports guide

Bug description

Issue described in hakimel/reveal.js#3771
Fixed in hakimel/reveal.js@aa9dfc7
Updating reveal.js dependency to ≥5.2.1 should fix

Steps to reproduce

1. Compile this presentation:

---
title: "Untitled"
format: 
  revealjs:
    lightbox: auto
---

## Quarto

```{r}
plot(1:10)
```

2. Start speaker view

3. click the plot to turn on lightbox

4. Observe the fullscreen view does not change

Actual behavior

Lightbox does not engage in the fullscreen view

Expected behavior

The fullscreen view and speaker view should stay synced
