Markdown Remark with TOML support

This is a, hopefully temporary, fork of @astrojs/markdown-remark which adds support for TOML frontmatter in your Markdown (.md) and MDX (.mdx) files.

If you like the idea, then you can follow the PR here: https://github.com/withastro/astro/pull/12850

To use it, you can add the following to your package.json file.

"overrides": {
    "@astrojs/markdown-remark": "npm:@bate.dev/[email protected]"
}

I would prefer not to maintain this over time, so hopefully it can become part of the offical offering. Go lend your support.
