Render LaTeX

[albertoperdomo2]

This PR introduces LaTeX equation rendering capability to AstroPaper, enhancing its functionality for technical and scientific writing. By integrating KaTeX, we now support rendering of both inline and block LaTeX equations in Markdown files.

I do think this will enlarge the use of AstroPaper in the scientific community.

Many technical bloggers and documentation writers need to include mathematical equations in their content. Adding LaTeX support significantly expands AstroPaper's usefulness for these users, making it a more versatile platform for a wider range of creators.

Changes Made

• Updated astro.config.mjs to include remark-math and rehype-katex plugins.
• Modified the Layout.astro file to include KaTeX CSS.
• Added necessary dependencies (rehype-katex, remark-math, and katex) to package.json.
• Created a sample Markdown file demonstrating LaTeX usage.

I love what you’ve done and agree that this would be useful for many users. However, I think it might be better suited as a (docs) blog post rather than a default feature, as LaTeX syntax seems specific to certain use cases, like the blog post you've written.

How about creating a docs blog post for what you've implemented so far? This way, we avoid adding additional dependencies to the project, while users who want to use LaTeX syntax can follow along with the guide.

@satnaing yep, I noticed the emphasis on the minimal aspect of AstroPaper. I'll change the PR and create a simple blog post with instructions to enable LaTeX rendering.

@albertoperdomo2
I made some changes to this PR.
You can check whether the syntaxes are OK or not.
If everything's fine, I'll merge it.
