fix issue in books when page-footer is a link

Change has been made in 90e04f4 following discussion in #3441 to allow `href` being a .qmd file to be rendered.

Though when `href` is a link, it made Windows fails because our globExpanson on Linux knows to ignore https:// one, and on Windows it doesn't. Deno behavior for `expandGlobSync` - see discussion in issue #8737)
