Subject: [PATCH 1/2] Fix non-deterministic tcolorbox option ordering in LaTeX
 output

`tColorOptions()` used `pairs()` which iterates Lua table keys in
non-deterministic order, causing `.tex` output to differ between
renders of the same document. Switch to `spairs()` for sorted
iteration so tcolorbox options are always emitted alphabetically.

+- ([#14017](https://github.com/quarto-dev/quarto-cli/issues/14017)]): `tColorOptions()` in .tex file will now always have options in alphabetical order. Previously, they were in random order leading to a different .tex intermediates for identical .qmd.
