Add <meta property="og:locale:alternate" content="" /> Support to Metadata Object and generateMetadata Function

[MicaelPiresCom]

Goals

1. Add <meta property="og:locale:alternate" content="" /> support to metadata object and generateMetadata function.

Non-Goals

No response

Background

It's not possible to add it via other: { custom: 'meta' }, as it returns <meta name="custom" ... instead of <meta property="custom" ... as it is needed in Open Graph tags.

Proposal

The openGraph: { locale: '' } can be changed to support either a string or an object. The object could support locale and alternates which would be an array of strings.

BUT

If there is already alternates (<link rel="alternate" ...) defined, just reuse that data and add the og:locale:alternate tags automatically.

I have been struggling with this as well. Since we need to implement https://developers.facebook.com/docs/marketing-api/catalog/guides/microdata-tags/ this and it is at the moment not possible with generateMetadata
