`df-print` ignored on Confluence

Bug description

When publishing to Confluence, the df-print option [kable, tibble, paged] is ignored. (It is applied to the preview, however, and at least kable and tibble outputs are possible on Confluence. I haven't tested, whether paged is supported on Confluence).

Steps to reproduce

Publish the following to Confluence:

---
title: "confluence df-print kable"
format: 
  confluence-html:
    df-print: kable
---

```{r}
head(mtcars)
```

Expected behavior

The table output is rendered as specified in df-print (as in the preview, in this case (kable) like a markdown table):

Actual behavior

The table output is rendered with the default S3 method for the data frame.

Start by publishing the provided R and Confluence example, then compare its output with the preview. Trace how the confluence-html format handles the df-print option for kable and tibble output. Done means the Confluence table uses the selected df-print method rather than the default data-frame rendering.
