Support output-location: column in HTML documents

[maxdrohde]

In the reveal.js format, we can use the output-location: column YAML option to show the output in the column next to the code, instead of the standard location below the code (see: https://quarto.org/docs/presentations/revealjs/#output-location)

It seems to me like this is only possible in the reveal.js format. It would be great to have this supported in HTML documents as well.

To clarify, I see that this is supported for plots and tables using column: margin. But the behavior is different for text output. I would like all the code to be in the main column, and all the output in the margin.

Example

```{r}
#| column: margin
plot(1:5)
```

```{r}
#| column: margin
print(1:5)
```

Output

This definitely makes sense- I created an issue to track making this change!
