ci: Skip build job for markdown-only PRs

Fixes issue where job_build would run for PRs that only change markdown files.
This was accidentally broken in #10421 when the changed_any_code check was
removed from the last condition.

This change restores the original behavior: markdown-only PRs will skip the
build job while still running formatting checks in job_check_format.
