update-book2.rb: gracefully warn about missing files, but continue

When a file goes missing but is still referenced, as was the case with progit/progit2-zh#507, we do not want the entire book rendering business on https://git-scm.com/ to halt before that bug is fixed. Let's instead warn about this and continue to render the book. Signed-off-by: Johannes Schindelin <[email protected]>
