Support more code type

Is your feature request related to a problem? Please describe

When I write code block which type rarely seen in markdown file, like diff, the console throw an error in dev mode

[nuxt] [request error] No grammar provided for <source.[the name of the rarely seen code type]>

Describe the solution you'd like

It seems this error throw from shiki, how to config it to ignore the rarely code type instead of throw an error

Describe alternatives you've considered

Additional context

the markdown wrting code block as fellow, its type is diff, github and VS Code built-in markdown editor preview mode can render this type

but the Nuxt console throw an request error and then a 500 Internal Server Error

and the page cannot render correct

This issue comes from Shiki itself. check upstream issue shikijs/shiki#257

Meanwhile, you can use highlight.preload to preload all required language. Check my comment #1225 (comment)

just add 'diff' in content.highlight.preload is still not working, the console throw another error [nuxt] [request error] No grammar provided for <source.ts>

Maybe it needs more setting

[farnabaz]

When you use preload config, you need to define list of languages you are using in your contents.

defineNuxtConfig({
  content: {
    highlight: {
      preload: ['diff', 'ts', 'js', 'css', ...]
    }
  }
})

I just create a PR(#1278) to prevent this bad behavior, in next release you will not need to add ts or js into preload options.
