Float crossref breaks longtable in a quarto PDF book

[jonpeake]

Bug description

When rendering a book in PDF form and including a longtable in a custom float reference div, the table does not break across multiple pages. I believe this is an extension of #7604, which appears to be fixed for some formats, but not book format.

Steps to reproduce

Create quarto book project, add following to introduction.qmd:

::: {#apptbl-tbl1}
```{r}
knitr::kable(cars, format = "latex", longtable = T)
```

This is a long table
:::

Expected behavior

Table should render in long format, i.e., split across pages

Actual behavior

Table produces on one page, cut off at bottom

Longtables are unfortunately not supported in custom crossref and there's nothing we can do about it. The latex longtable package hard-codes the crossref counter for the table environment, and so we need to convert longtable environments into tabulars before rendering.

Well that is certainly a bummer, but I appreciate the quick response. Thank you!
