Use og:image instead of og:image:url (#46570)
x-ref: https://github.com/vercel/next.js/discussions/46545
In the open graph protocol spec, `og:image` and `og:image:url` are identical. But some platform might don't have full support for it.
We change it back to render `og:image` as it's the most common and compatible format, also easy to align with the code docs
