Open external links in a new tab using rel="noopener"
Before the Hugo migration, external links opened in a new tab using
rel="noopener noreferrer". We had to remove
noopener because Hugo didn't support it. But @grote has pointed out that it's now possible with Hugo:
Hugo 0.62 now supports Markdown Render Hooks which can be used for things like adding
rel="noopener"attributes on all links.
