[LaTeX] Multiple tables in cells are counted as subtables while not in Typst or HTML.

It seems this is again happening for LaTeX

Discovered while looking at failing test for

• #13249

It happens we have one https://github.com/quarto-dev/quarto-cli/blob/28a208dbe88c5557cbab9b5d86aad2d38d784716/tests/docs/smoke-all/2023/10/18/7267.qmd but not really testing anything

HTML output

Typst output

LaTeX output

So this needs to be handled again. Maybe differently considering new Pandoc.

This is the simpler Markdown that reproduce the differences

# Table 3 

::: {#tbl-table3}

::: {}


| Column 1 | Column 2 | Column 3 |
|----------|----------|----------|
| Value 1  | Value 2  | Value 3  |

• Check if we have ff-matrix for subtables.
• Adapt test at https://github.com/quarto-dev/quarto-cli/blob/main/tests/docs/smoke-all/2023/10/18/7267.qmd too
