Change cmidrule regex to non-greedy

When running the script

library(tinytable)
library(modelsummary)

data(cars)

sessionInfo()

modelsummary(
  list(
    mod = lm(speed ~ dist, data = cars),
    mod = lm(speed ~ dist, data = cars),
    mod2 = lm(speed ~ dist**2, data = cars),
    mod2 = lm(speed ~ dist**2, data = cars)
  ),
  stars = TRUE, gof_omit = "IC|Adj|F|RMSE|Log", output = "tinytable",
  vcov = "classical"
) |>
  theme_tt("tabular") |>
  group_tt(j = list("Linear" = 2:3, "Poisson" = 4:5)) |>
  save_tt("table.tex", overwrite = TRUE)

the resulting table is:

\begin{tabular}{lllll}
\hline
& Linear &  & Poisson &  \\ \cmidrule(lr]{2-3}\cmidrule[lr){4-5}
& mod & mod  & mod2 & mod2  \\ \hline
(Intercept) & 8.284*** & 8.284*** & 8.284*** & 8.284*** \\
& (0.874)  & (0.874)  & (0.874)  & (0.874)  \\
dist        & 0.166*** & 0.166*** & 0.166*** & 0.166*** \\
& (0.017)  & (0.017)  & (0.017)  & (0.017)  \\
Num.Obs.    & 50       & 50       & 50       & 50       \\
R2          & 0.651    & 0.651    & 0.651    & 0.651    \\
Std.Errors  & IID      & IID      & IID      & IID      \\
\hline
\end{tabular}

The cmidrules are wrong here because of a greedy regex inside theme_tt. It matches the first cmidrule all the way to the end of the second cmidrule (and possible other cmidrules between). This PR changes the regex to a non-greedy version which fixes the issues.
