Host PDF in About page links

[jmgirard]

Related to #790, I want to add a PDF to an "About" page and am having trouble getting it to route properly.

This is my YAML in ./people/girard.qmd:

---
title: "Jeffrey Girard"
resources: 
   - "girard_cv.pdf"
about:
  template: jolla
  links:
    - icon: file-earmark-text
      text: vitae
      href: girard_cv.pdf
---

This results in the following in ./people/girard.html:

<a href="http://localhost:3553/girard_cv.pdf" class="about-link">
    <i class="bi bi-file-earmark-text"></i>
     <span class="about-link-text">vitae</span>
</a>

which doesn't work in my case because the href should be to http://localhost:3553/people/girard_cv.pdf locally and https://jmgirard.github.io/reponame/people/girard_cv.pdf when published via GitHub Pages.

The following works locally, but not when published:

---
title: "Jeffrey Girard"
resources: 
   - "girard_cv.pdf"
about:
  template: jolla
  links:
    - icon: file-earmark-text
      text: vitae
      href: ./people/girard_cv.pdf
---

The following works when published, but not locally:

---
title: "Jeffrey Girard"
resources: 
   - "girard_cv.pdf"
about:
  template: jolla
  links:
    - icon: file-earmark-text
      text: vitae
      href: ./reponame/people/girard_cv.pdf
---

In an ideal world, I could just put href: girard_cv.pdf and quarto would be smart enough to work locally and when published.
