docs-infra: force latexmk through per-glyph/per-image LaTeX errors in PDF build
pdflatex hard-errors on the Devanagari etymology text in
docs/introducing/history.md ("! LaTeX Error: Unicode character व
(U+0935) not set up for use with LaTeX") and separately cannot embed
several pre-existing .webp images (no BoundingBox) — both previously
undiscovered because the Devanagari error always halted the build
first. latexmk -f (force mode) + pdflatex -interaction=nonstopmode
makes the build tolerate both classes of per-glyph/per-image failure
and finish, matching how ReadTheDocs has always built this project's
PDF (verified against the live docs.vyos.io PDF: same Devanagari
glyphs blanked, same ~4 images embedded out of 2000+ pages).
latexmk exits non-zero in force mode even on a fully-produced PDF, so
the workflow step now verifies the artifact itself (exists, >2MB)
instead of relying on the command's exit code.
