Bing index won't use property="og:description" from the meta tag in _includes/seo.html

Is your feature request related to a problem? Please describe.
Bing will complain of SEO issues unless a <meta name="description" content="..."> tag is present.

Describe the solution you'd like
You can either add another meta tag inside {% if page.excerpt %} in _includes/seo.html, or write the meta tag like this:
<meta property="og:description" name="description" content="{{ seo_description }}">. I have tested both methods:

• Google is fine with og:description or nothing at all
• Bing supports only meta tags with name="description" present. Bing is also fine with the option where both name="description" and property="og:description" are present.

Additional context
At least the crawler used by the https://www.bing.com/webmasters site is problematic in this context, I don't know about IndexNow.
