[gatsby-remark-images] allow captions on externally hosted images

[mguida22]

Summary

Allow for captions on images that are loaded from an external source.

Basic example

with this config

options: {
  showCaptions: true
}

show captions from this markdown

![flowers](https://i.imgur.com/7DxkqAV.jpg "paintbrush flowers")

Motivation

It'd be great to show captions on images that are hosted on other sites. This would allow consistent writing of markdown alt/title/captions regardless of how image is served.

It looks like here it's ignored if it's not a relative path. I'd be happy to make a PR for this if it's desired!
