Add Generic Data Typing for matter Frontmatter Parsing about gray-matter

[jrock2004]

I am trying to find where but someone posted this code snippet and its made my life easier

import matter from 'gray-matter';

const typedMatter = <T = any>(markdown: string) => {
  const rawMatter = matter(markdown);

  return {
    ...rawMatter,
    data: rawMatter.data as T,
  };
};

export default typedMatter;

I should mention that I'm doing a type casting using as and this doesn't make me happy but it does the job.

type Content = GrayMatterFile<string> & {
  data: { title: string, description: string }
}
const content = parsedContent as Content

I would enjoy a similar feature. As is, I'm just assigning a new object from my file parsing function using just the fields I expect, and returning that, but being able to specify the type on the return from matter() would be super handy.

Actually, it looks like this issue has been brought up before, and has been open for a long time with no feedback from the library author. Kind of disappointing.
