Improve linting to show that out-width and out-height are being ignored in revealjs when stretch is activated (globally or per slide)

[EmilHvitfeldt]

Bug description

using out-width and out-height in chunks in revealjs documents appears to be ignored.

Steps to reproduce

---
format: revealjs
---

## out-width: 1000px

```{r}
#| out-width: 1000px
library(ggplot2)

ggplot(mpg, aes(displ, hwy, colour = class)) + 
  geom_point()
```

## out-width: 100px

```{r}
#| out-width: 100px
library(ggplot2)

ggplot(mpg, aes(displ, hwy, colour = class)) + 
  geom_point()
```

Expected behavior

I expected the figure would change the output of the figure files

Actual behavior

they appear unchanged

This is because by default images are stretched, see https://quarto.org/docs/presentations/revealjs/advanced.html#stretch.

It would be great for us to be able to detect this and issue a warning in our linter.
