Fix jsonify name in seo.html application/ld+json script

[d00616]

When the name includes " then the resulting schema is invalid. This is a fix.

Thanks for the PR.

Question, would the jsonify filter be a better option than xml_escape, or does that not properly escape double quotes?

To reproduce, set the "name:" field to a string "This is a "Test"" and validate the result via https://search.google.com/structured-data/testing-tool

Without this fix seo.html produces something like:

<script type="application/ld+json">
    {
      "@context" : "http://schema.org",
      "@type" : "Organization",
      "name" : "This is a "Test"",
      "url" : "http://1.2.3.4:4000",
      "sameAs" : null
    }
  </script>

jsonify is the better option.

@d00616 You have to remove the quotes around the variable. To keep things consistent I'd prefer to use jsonify like the others.

This would be the change:

<script type="application/ld+json">
{
  "@context": "http://schema.org",
   "@type": "{% if site.social.type %}{{ site.social.type }}{% else %}Person{% endif %}",
   "name": {{ site.social.name | default: site.name | jsonify }},
   "url": {{ seo_url | jsonify }},
   "sameAs": {{ site.social.links | jsonify }}
}
</script>

Which produces this valid JSON:

<script type="application/ld+json">
{
  "@context": "http://schema.org",
  "@type": "Person",
  "name": "This is a \"Test\"",
  "url": null,
  "sameAs": null
}
</script>

It's changed.
