try to add duplicate warning definition only for knitr

[cderv]

In knitr, warning: 'NA' is supported. How to allow that for auto completion ?

---
title: "test"
format: html
---

```{r}
#| warning: NA
warning("Test")
```

@cscheid Do you know if our schema would allow to get a specific YAML validation for an option in cell

while this option is also used as document-execute.

The way I tried here, seems to have remove the execute part

while correctly added under cell

Normaly warning is also in execute

So do we have a way to have two warning definition with our schema ?

Thank you !

A note that the document in example

---
title: "test"
format: html
---

```{r}
#| warning: NA
warning("Test")
```

Is not supposed to be rendered and should have a validation error at rendering time.

But this is not happening because of

quarto-cli/src/core/schema/validate-document.ts

Lines 113 to 116 in 46d71b0

	const fullCell = mappedString(cell.sourceVerbatim, [{
	start: lang.length + 6,
	end: cell.sourceVerbatim.value.length - 3,
	}]);

End line problem 😁 \r\n on Windows, so start should be + 7 not 6.

Fixing this will probably make a lot of document fails, at least those using valid knitr option but unknown to validation. We'll see.

I'll probably open a new PR to solve this issue.

#12151 will fix the YAML validation, but this means that warning: NA won't work in .qmd anymore, until this issue of scoped definition is solved.

For reference, similar problem with echo and eval. Our schema focument more than just boolean, but we don't only it
