feat!: migrate to vitepress

This PR is created based on conversation on Twitter.

With this proof of concept (although I migrated almost everything already), you can preview VitePress' look-and-feel and developer experience.

1. Update dependencies

   pnpm install

2. Run dev server

   pnpm run dev

3. Build the website

   pnpm run build

Here are some information about VitePress and developer experience:

• Obviously, VitePress uses Vue, while Docusaurus uses React
• Almost all features can be migrated except Docusaurus' blog feature
  • We have to make up post list page as needed, which is not included in this PR yet
  • We have to calculate reading time as needed, which is not included in this PR yet
  • We have to add post titles to .vitepress/config.ts manually for them to be shown in sidebar (we might be able to do some automation)
• I added 2 custom components to make up missing design (see .vitepress/theme/components directory)
• We have to set up Prettier for .vue files (not included in this PR yet)
• We have to set up some lint for CSS in .vue files (browserslist is temporarily deleted in this PR for simplicity)

VitePress has some features that you might get interested in:

• Local search
• Team page
• Badge
• Carbon ads

@Boshen

Would you run CI again?

@Boshen

Thank you for merging!

From now on, I will add some missing features and improve developer experience 🙋‍♂️
Additionally, if you want, we could discuss information architecture including oxc-project/javascript-parser-in-rust#19, as another issue.

@NozomuIkuta I gave you write access to this repo https://github.com/oxc-project/oxc-project.github.io/invitations

I'm going to dump content as time goes on. You are free to adjust things as you fit, no permission required.

Thank you so much!!
I'm honored to be given such a great opportunity.

Although I'm not yet familiar with Rust enough to contribute to the core, I will do my best so that Oxc will be recognized and used by more people in the community.
