gatsby-transformer-remark - add additional helpful fields to MarkdownRemark nodes from parent File node

[kimbaudi]

Currently, MarkdownRemark nodes created from gatsby-transformer-remark plugin provides fileAbsolutePath field and I use it to filter markdown nodes

{
  allBlogPost: allMarkdownRemark(
    filter: { fileAbsolutePath: { glob: "**/blog-posts/**" } }
  ) {
    nodes {
      fileAbsolutePath
    }
  }
}

But if gatsby-transformer-remark plugin also provided sourceInstanceName, relativeDirectory, name fields from its parent File node, then my graphql query to filter markdown nodes could be simplified to this:

{
  allBlogPost: allMarkdownRemark(
    filter: { fileSourceInstanceName: { eq: "blog-posts" } }
  ) {
    nodes {
      fileSourceInstanceName
    }
  }
}

---

It would be awesome if gatsby-transformer-remark could provide the following nodes:

allMarkdownRemark {
  nodes {
    fileAbsolutePath
    fileSourceInstanceName
    fileRelativeDirectory
    fileName
  }
}

or better yet:

allMarkdownRemark {
  nodes {
    file {
      absolutePath
      sourceInstanceName
      relativeDirectory
      name
    }
  }
}
