[ChristopherChudzicki]

See #1130 for motivation

Acceptance Criteria

• Convert all links wrapping resource shortcodes to href / href_uuid properties on the resource

Example

# Within-site link:
[{{< resource image-uuid >}}]({{< baseurl >}}/resources/lgo_map)

# Similarly, external (and cross-site) links
[{{< resource image-uuid >}}](https://externalurl.org)
# Become
{{< resource image-uuid href="https://externalurl.org" >}}
