### Bug description

I followed the example at https://quarto.org/docs/publishing/confluence.html to publish the default Quarto file confluence-demo.qmd, with title specified in the yaml as "Confluence Demo". The preview resulting from `quarto preview confluence-demo.qmd` looks correct. The page that makes it to Confluence using `quarto publish confluence confluence-demo.qmd` ends up with a random hash added to the title, for example "Confluence Demo 58b33578". This hash changes to a different random value when republished.

### Steps to reproduce

````qmd
---
title: "Confluence Demo"
format: confluence-html
---

## Quarto

Quarto enables you to weave together content and executable code into a finished document. To learn more about Quarto see <https://quarto.org>.

## Running Code

When you click the **Render** button a document will be generated that includes both content and the output of embedded code. You can embed code like this:

```{r}
1 + 1
```

You can add options to executable code like this

```{r}
#| echo: false
2 * 2
```
