Attributes (`href`, `imagesrcset`) not properly encoded in `link` `preload` tags (leading to `unrecognized-char-ref` errors in Nuxt Hints)

[codeflorist]

Consider this usage of NuxtImg:

<NuxtImg
  src="/my-image.png"
  :modifiers="{ w: 200, q: 10 }"
  preload
/>

This results in the following link tag in the html head:

<link
  rel="preload"
  as="image"
  href="/_ipx/w_200&q_10/coopsman.png"
  imagesrcset="/_ipx/w_200&q_10/coopsman.png 1x, /_ipx/w_200&q_10/coopsman.png 2x"
/>

The ampersand in the URLs should be encoded as & and Nuxt Hints (via the html-validate package) lists this as an error:
hints:htmlValidate:warn [html-validate] unrecognized-char-ref at inline:39:24 - Unrecognized character reference "&q"
