conflict with rmarkdown::paged_table

[richardjtelford]

I have a quarto book that has a table using rmarkdown::paged_table(). This worked fine until I add webexercises with add_to_quarto(). I think there is some sort of conflict in the javascript, but I don't know how to diagnose that.

Example table:

```{r}
rmarkdown::paged_table(palmerpenguins::penguins)

A hotfix is to add this line in webex.js in the window.onload function:

  PagedTableDoc.initAll();

I added that after update_total_correct();
