Example of Attributes Render Hook in v0.82.0

Support for attributes is limited to headings, code blocks, and block elements. Links and images are inline elements. See https://discourse.gohugo.io/t/is-it-possible-to-use-attribute-lists-with-render-hooks/31374/6.

See https://discourse.gohugo.io/t/32131/5 for a workaround.
