[latex] output: email autolinks is missing a pair of curly braces

file that demonstrates the issue: [repro.tex](https://github.com/user-attachments/files/24280598/repro.txt) latex output for email autolinks is incorrect: input [repro.md](https://github.com/user-attachments/files/24280603/repro.md): `<example@example.com>` output of `cmark --to latex repro.md`: `\href{mailto:example@example.com}\nolinkurl{example@example.com}` expected (matching pandoc): `\href{mailto:example@example.com}{\nolinkurl{example@example.com}}` difference: the "clickable link" covers a sliver instead of covering the entire text area example: [repro.pdf](https://github.com/user-attachments/files/24280606/repro.pdf) tested with: cmark `cmark 0.31.1 - CommonMark converter` lualatex `This is LuaHBTeX, Version 1.18.0 (TeX Live 2024/Alpine Linux)` pdf reader: zathura `zathura 0.5.14 girara 0.4.5 (runtime: 0.4.5) (plugin) djvu (0.2.11) (/usr/lib/zathura/libdjvu.so) (plugin) pdf-mupdf (0.4.4) (/usr/lib/zathura/libpdf-mupdf.so)` (browser behaves differently) code in question: https://github.com/commonmark/cmark/blob/32564a47f10202b69eee24f4946476c8865de1e6/src/latex.c#L412
