Added image fallback and site icon/title to <GhPostBookmark> (#2401)

no issue

- adds `{{get-setting "key"}}` helper to make settings available in templates without needing a backing class
- updated `<GhPostBookmark>` component
  - if post feature image isn't present, fall back to site cover image
  - add site icon (if present) and title to the details line
  - removed author image
