Introduce a Prettier plugin to format Slidev's extension well

Related #854

I wrote one in https://github.com/KermanX/prettier-plugin-slidev. (Not published to npm)

I don't know whether it is better to make it a package in the monorepo or a separate repository in the slidevjs org.

TODO:

• merge PR: feat: add SlideInfoBase.frontmatterRaw #1268 (Add a new field SlideInfoBase.frontmatterRaw to preserve comments in frontmatter)
• unit tests

Known issues:

1. In the Latex code block, the line highlighting part will be moved to the next line by Prettier like this:

$$
{1|3|all}
\begin{array}{c}
...
\end{array}
$$

I think it is hard to fix. Thankfully, this doesn't break the line highlighting functionality.

@antfu I think https://github.com/KermanX/prettier-plugin-slidev is ready for a release. Should the repository be transferred to the slidev organization, and then publish a release? (I can't do it myself because I don't have the permission)

Looks promising! Just invited to join the team!

Up to you if want to transfer the repo to this org, or want to migrate it inside this monorepo :)

I have transferred it to https://github.com/slidevjs/prettier-plugin, and published it as prettier-plugin-slidev@1.0.0. (Invited @antfu to the package)
