Quarto callouts

[peterdesmet]

I've been looking for a way to style/highlight notes in the vignettes. This is possible with quarto callouts:

::: {.callout-info}
You can use callouts
:::

• In a vignette, this will look as before (regular text)
• In pkgdown, this will look as before, since callouts are not supported yet, but it seems that will be the case at some point in the future. I don't think we'll have to convert our .Rmd to .qmd, since a Quarto feature like [Small caps]{.smallcaps} already works.

We could already make it work by using:

::: {.alert .alert-info}
You can use alerts
:::

Which renders like:

But I think it's better to not use this temporary solution, but use callouts. It doesn't affect the readability now + will look better once pkgdown is updated.

This PR also updates a step in frictionless.Rmd where a resource is replaced.
