feature: add markdown plugins to blogs for better customisability.

[abheektripathy]

We could setup some mdx plugins with contentlayer for better blog customisability.

these would be a good place to start.

1. remark-gfm to support GitHub Flavored Markdown.
2. rehype-prism-plus to render syntax highlighting in code blocks.
3. rehype-code-titles to render code block titles.
4. rehype-accessible-emojis to provide accessibility to emojis.

I'd be happy to give this a shot. May I work on this?

I tried to implement this, but I think is bugged with the support for gfm right now.
