[feature] Ability to specify alt text for link images

[pete-woods]

What happened?

hugo-theme-stack/layouts/partials/article/components/links.html

Line 24 in 9e96c6e

<img src="{{ $permalink }}" loading="lazy">

I think it needs adding here? This is setting off my accessibility linter at the moment.

title: Links
links:
  - title: Somewhere
    description: Description
    website: https://example.com
    image: https://example.com/image.png
    alt: This is an image of something # This would be a new attribute
