1. Concise description of the bug

Hi! Thank you so much for maintaining this package! When using modelsummary::modelsummary() in Quarto or RMarkdown, I run into a weird issue: with caching enabled, tables that were generated fine upon the first run are now throwing an error:

ERROR: 
compilation failed- error
LaTeX Error: Environment talltblr undefined.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              

l.207 \begin{talltblr}
                      [         %% tabularray outer open 

2. Minimal reproducible example using publicly available data and the bare minimum code and libraries needed to reproduce the bug.

# Testing

```{r}

data(ChickWeight)

m1 <- lm(weight ~ Time, data = ChickWeight)
m2 <- lm(weight ~ Time + Diet, data = ChickWeight)

modelsummary::modelsummary(
  list(m1, m2),
  coef_map = list(
    Time = "Time (days)",
    Diet = "Diet"
  ),
  stars = TRUE)

Here's a guess: When compiling a Quarto, if you actually run modelsummary() command, it will add all the necessary LaTeX packages to your preamble automatically. If you cache the table, you do not run the command, and the necessary prerequisites are not added to the preamble. Thus, you need to add LaTeX commands (documented in the man page) to the preamble manually in the YAML.

Loading tabularray to header does indeed fix the issue - guess this should have been obvious. Thank you!
