Package request: texlive-latexextra

Add texlive-latexextra to the archsetup script's package list.

Why: The career project's resume build system (Makefile) uses pdflatex to generate
PDFs from LaTeX source. The resume.tex files use the enumitem package (for itemize
list formatting), which is provided by texlive-latexextra. Without it, pdflatex
fails with "Undefined control sequence" on \setlist.

Already installed: texlive-basic, texlive-bin, texlive-binextra,
texlive-fontsrecommended, texlive-latex, texlive-latexrecommended

Install command: pacman -S texlive-latexextra
