fix: missing max-video-preview

[gmaxlev]

The type declaration specifies maxVideoPreview, but it is not added to the meta tags. This pull request aims to fix that.

Hi @gmaxlev You don't need to add extra code if you want to add additional meta tags, you can use the additionalMetaTags property.

Here's an example for meta keywords:

additionalMetaTags: [
  {
    name: 'keywords',
    content: processedKeywords,
  },
],

or in your case:

additionalMetaTags: [
  {
    name: 'max-video-preview',
    content: maxVideoPreview.toString(),
  },
],
