### Bug description

Hi there, I noticed that my Quarto site's name is wrong in Google search results. The site name is circled here in green:

![](https://developers.google.com/static/search/docs/images/site-name.png)



### Steps to reproduce

When I google for things on the Shiny website, which has a site name of "Shiny," sometimes it says "Shiny app" or "R Shiny," which is especially disappointing because its real name is "Shiny for R."

Here is a Google result for "shiny posit"

### Expected behavior

That site name on Google should just be "Shiny".

The [Open Graph](https://ogp.me/#optional) website says the meta property should be:

`<meta property="og:site_name" content="Shiny">`

### Actual behavior

What Quarto creates from the _quarto.yml file is:

`<meta property="og:site-name" content="Shiny">`

I think this might be as simple as changing the dash in "og:site-name" to and underscore "og:site_name"
