[BUG] linkToMarkdown parameter doesn't seem to have any effect

[wblondel]

Describe the bug

Hello,

The linkToMarkdown parameter in the [params][page] section doesn't seem to have any effect.

I enabled it by setting it to true, and added the markdown format in the page outputs.

The markdown documents are generated but no link appears in the footer.

Environment

• Browser: Edge 93.0.910.5 dev
