 In #37171 the use of the `preconnect` resource hint was added for core
 themes that use Google Fonts. However, what was missing was also including
 the `dns-prefetch` resource hint. The `preconnect` resource hint is not
 supported by older browsers, so including `dns-prefetch` ensures that
 they'll also get some performance benefit.

 See MDN docs for [https://developer.mozilla.org/en-US/docs/Web/Performance
 /dns-prefetch#best_practices Best Practices] that recommend pairing
 `preconnect` with `dns-prefetch`.
