Quarto Callout Blocks support

[dmetivie]

It seems that Quarto format for callout blocks is different that usual markdown flavor, see here.

Example instead of

!!! note
   My note

It is with Quarto

::: {.callout-note}
My note
:::

Currently, using Literate.jl with Quarto flavor on

# !!! note
#     My note

produces in the qmd

> **Note**
>
> My note

Which is not exactly the intended result.

It would be nice to support all the callout blocks (note, warning etc) !

Ok!
I am no regex expert but (using your code) does the following would be acceptable

adm_to_QuartoCallout = function (s)
    m = match(r, s)::RegexMatch
    io = IOBuffer()
    print(io, "::: {.callout-") # to open the callout
    print(io, string(m[:type]))
    println(io, "}") # not sure how to detect the Quarto `collapse` option if any
    if (title = m[:title]; title !== nothing)
        print(io, "## ")
        print(io, title)
    end
    for l in eachline(IOBuffer(m[:lines]); keep = true)
        print(io, replace(l, r"^#     " => ""))
    end
    print("\n :::") # to close the callout
    return String(take!(io))
end

with a isQuartoFlavor option somewhere ? Or another kwarg to select the type of admonitions wanted.
