basics.location.address should be a string[]?

[SethFalco]

Currently, basics.location.address is a string, and it's documented that users should use \n to insert line breaks.
I think it'd be better to allow users to define the address lines separately with a string[]. (string can still be permissible)

The change would be backward compatible, theme templates would just have to check if it's an array or a string literal.

{
  "basics": {
    "location": {
      "address": "International House\n24 Holborn Viaduct\nLondon, EC1A 2BN"
    }
  }
}

{
  "basics": {
    "location": {
      "address": [
        "International House",
        "24 Holborn Viaduct",
        "London, EC1A 2BN"
      ]
    }
  }
}

The change in the schema would probably look like the following, and again, would be backward compatible.

{
  "title": "Address",
  "description": "Your physical address.",
  "oneOf": [
    {
      "type": "array",
      "description": "The address lines for your physical address.",
      "items": {
        "type": "string",
        "description": "A single line from the physical address."
      }
    },
    {
      "type": "string",
      "description": "To add multiple address lines, use \n. For example, 1234 Glücklichkeit Straße\nHinterhaus 5. Etage li."
    }
  ]
}

Alternatively, we could also just deprecate the old way of doing it as well?
