Describe the bug
Hello,

Could be a great addition to automatically add @ to the beginning of the twitter site. Otherwise, a type could alert dev that he should add one.

For reference: developer.twitter.com/en/docs/twitter-for-websites/cards/guides/getting-started

I think it's a good idea :)

In terms of implementation though, I think adding an Unhead plugin for this is a bit much.

If we wanted to solve this in Nuxt a good place to handle it would be in https://github.com/harlan-zw/nuxt-seo-experiments, having it as a standalone plugin then would be fine.

Otherwise, I was already considering working on a development Unhead plugin that would provide warnings when using tags incorrectly, this could be one of the rules.

Closing in favour of #394
