pr template: ask contributors to review and copy-edit AI contributions 82944918 parent e1365d7f

The goal is to nudge contributors towards taking on the burden of understanding and editing any AI-generated work they are trying to get reviewed. AFAICT, jj is currently less overwhelmed with low-quality AI contributions than to some other projects, but it started to happen occasionally. For now, this is partly an experiment as opposed to a fixed rule. Will the people who most need this guidance read it and benefit from it? Hopefully, they'll try to or will ask questions. I considered also adding a clarification to the second point, suggesting something like "If in doubt, delete all the AI-generated text and rewrite it in your own words", but that point was already getting long. We could add something like that later. See https://github.com/jj-vcs/jj/pull/8897#discussion_r2815120348 for some reasons I didn't want to require disclosing whether people used AI tools while preparing the PR.
