Confluence - File attachment links broken

[soneill-pure]

Bug description

Links to file attachments result in broken links when publishing to Confluence.

Steps to reproduce

---
title: "Reproducible Quarto Document"
format: confluence-html
---

[Fake Excel workbook](test_files/fake_excel_workbook.xlsx)

Expected behavior

File attachment link should lead to download when clicked on in Confluence.

Actual behavior

When I inspect code on Confluence browser, the macro seems formulated correctly but the link to the attachment is broken

<ac:link>
   <ri:attachment ri:filename="test_files/fake_excel_workbook.xlsx" />
   <ac:plain-text-link-body><![CDATA[Fake Excel workbook]]></ac:plain-text-link-body>
</ac:link>

I am able to workaround by injecting the same macro code directly into the Quarto doc. If I do this, then the attachment link isn't broken in Confluence.

```{=confluence}
<ac:link>
  <ri:attachment ri:filename="test_files/fake_excel_workbook.xlsx" />
  <ac:plain-text-link-body><![CDATA[Fake Excel workbook]]></ac:plain-text-link-body>
</ac:link>

This seems to be a function of the type of file. I tried with .txt files and it works fine but with .dot the link is broken.

@soneill-pure how do you see the confluence code?

thanks FKG

@fkgruber in the top right of a Confluence page, I see a button for editing page source which shows the Confluence html
