Tom Foster d640853f9d ci(docs): Optimise build performance with caching and conditional Node.js
Skip installing Node.js entirely if v20+ is already available, otherwise
install v22. Add npm dependency caching with OS-specific cache keys using
the custom detect-runner-os action for proper cache isolation between
runners. Dependencies normally take just under 10s, so this should more
than halve the doc build time to free up runner slots.
