Hard breaks aren't reflected in output

[Kyle-Ye]

Description

See full issue here swiftlang/swift-docc#477

After swiftlang/swift-docc#633, swift-docc will emit LineBreak from swift-markdown into "\n". But swift-docc-render still does not treat the new line correctly.

      "type": "text"
    },
    {
      "text": "appear on two lines.",
      "type": "text"
    }
  ],
  "type": "paragraph"
}

I can help look into this. I'm thinking we would probably just want to map the inline text nodes with newline characters into <br> HTML elements.

I'll need to play with the DocC PR to see if we can rely on the newline always being in its own individual text node or if it could possibly be interspersed with other text.
