• Simplify the rollup config.
• Add the 'node:' prefix to explicitly indicate it requires a Node.js core module.
• Upgrade the workflows related to release processing in GitHub Actions to use Node.js v20.
• Upgrade the related actions of the github-actions package to use Node.js v20.
  • Upgrade the get-release-notes action.
  • Upgrade the prepare-node action.
