brace tables with typst:no-figure and typst:text attributes

[gordonwoodhull]

The combination of #9648 typst:text:* property output and #9778 typst:no-figure can cause fonts, text sizes, etc. to spill out of tables in Typst output.

This is because setting Typst text properties across a table requires #set text(...) outside the table, and previously we were relying on the figure to provide a scope.

Example:

<p>Paragraph before.</p>

<table typst:text:size="3em">
  <tr>
    <td>A</td>
    <td>B</td>
    <td>C</td>
  </tr>
</table>

<p>Paragraph after. Oops.</p>

produces

Paragraph before.

#set text(size: 3em); #table(
  columns: 3,
  align: (auto,auto,auto,),
  [A], [B], [C],
)
Paragraph after. Oops.

This PR provides the minimal fix, only adding an extra #[...] when the table has class typst:no-figure and also has typst:text:* attributes.

We work around this bug in Quarto in quarto-dev/quarto-cli#11113, but it would be better to have the fix in Pandoc because it could affect other users of these features.

This looks good. But instead of

#[#set text(size: 3em); #table(
  columns: 3,
  align: (auto,auto,auto,),
  [A], [B], [C],
)]

why not

#{set text(size: 3em); table(
  columns: 3,
  align: (auto,auto,auto,),
  [A], [B], [C],
)}

Isn't this a bit cleaner?

[gordonwoodhull]

Sure! The rest of the output uses content mode as a reasonable convention, but I'm a big fan of code mode in Typst.

Done.

P.S. I still think Haskell must have an abstraction to make the repeated logic of checking for empty lists in every function simpler?
