Liquid inside `{% schema %}` should not be visited by theme-check.

I think this is somehow related. But since theme blocks are introduced (I think) we can now connect a block value as a default. For instance, inside a section, I have this block:

"blocks": [
    {
      "type": "collection",
      "name": "t:sections.featured_collections.blocks.collection.name",
      "settings": [
        {
          "type": "collection",
          "id": "collection",
          "label": "t:sections.featured_collections.blocks.collection.collection"
        },
        {
          "type": "text",
          "id": "title",
          "label": "t:global.text.title",
          "default": "{{ block.settings.collection.title }}"
        }
  }
]

This is convenient and allow to automatically connect the title with the collection's title of the block.

Theme check report does not currently allow that though:

I am not sure if this is expected @charlespwd

This is a raw tag that considers liquid differently.
