Print quarto version in the generated document both in command line, knitr and jupyter generated document

Description

I am helping to develop some templates that need to support some feature between different quarto version, for the testing purpose how I can output/print quarto version the document was generated?
For quarto in Rstudio I can use

```{r} 
quarto::quarto_version()
```

but when I run test from command line (no R or without this library it will fail) but I might give me false results when I set in command line different path than the one shipped with Rstudio (though I am not so sure about this)
Is there any way to do it consistently?

In an HTML document you always have a meta element. From quarto.org:

What formats are you targeting?

its a pdf via typst template (easiest way is to install python/R and do this via chunk, bash call might be not OS portable)

Derived from the above:

return {
  ['qv'] = function(args, kwargs, meta)
    return table.concat(quarto.version, '.')
  end
}

---
title: "Quarto Playground"
format: html
shortcodes: 
  - version.lua
---

This is a playground for Quarto {{< qv >}}.

There is also QUARTO_VERSION exported by Quarto as a major.minor so you could do

---
title: "Quarto Playground"
format: typst
---

This is a playground for Quarto {{< env QUARTO_VERSION >}}.

But the lua filter above for shortcode is a really good way.
