🚀 Feature: Drop support for Node.js 18 after it goes EOL

[JoshuaKGoldberg]

Feature Request Checklist

• I have pulled the latest main branch of the repository.
• I have searched for related issues and found none that matched my issue.

Overview

Per https://endoflife.date/nodejs, Node.js 18 goes EOL April 30th 2025. Once this template bumps the minimum supported Node.js version to a 20.x minor:

• Many repos will be able to stop disabling n/no-unsupported-features/node-builtins (or at least its allowExperimental)
• We'll generally be able to assume newer JS features and Node.js APIs

Very exciting and real, tangible benefits to dropping support. But this is blocked:

• I'm not going to drop Node 18 support before then. This feature will be marked as accepting PRs in May 2025 at the earliest. ✅
• For repos that use --add-cta-transitions to automatically update to the latest create-typescript-app, the action will need to know to set the PR that drops Node.js 18 support as a feat: rather than a chore:
  • Tracked in: 🚀 Feature: Change Renovate create-typescript-app PRs to draft when changing package.json engines #2185

Now that #2229 is merged, this should now be doable without risk to downstream packages.
