Update node.js to v14.17.5

Editor assessment

The subject names the runtime being upgraded, node.js, and the target version v14.17.5, which fully determines the change. The chore type and deps scope are accurate for runtime maintenance, and no body is required for a routine automated bump. The Co-authored-by trailer crediting Renovate Bot is well formed, meaningful attribution and the only footer present. Style is clean: imperative phrasing, no trailing period, no ticket junk, moderate length, single language. A runtime version bump can carry compatibility risk, so a sentence on verification would have added value, but as routine maintenance the message communicates everything required and misleads nowhere.
