[5.x]: Craft native link field - expose entry title in GraphQL

[mtwalsh]

In Twig we can get the title of the linked entry via {{ entry.myLinkFieldHandle.label }} but I can't see a way of doing this with GraphQL as a URL is always returned.

I appreciate it would be easy enough to add a customTitle field, in fact we do already have one, but its purpose is to allow the user to set a label for the button that overrides the entry's title. This all works fine in Twig but we can't accomplish the same via GraphQL at the moment.

# GraphQL query
query {
  entry(id: 99) {
    ...on link_Entry {
      link1
      link2
      link3
    }
  }
}

// Response
{
  "data": {
    "entry": {
      "link1": "https://craftcms.com",
      "link2": "https://console.craftcms.com",
      "link3": "https://craft5.ddev.site/work"
    }
  }
}

P.S. Christmas definitely came early when you added this native Link Field, much appreciated! 👏
