Reduce support cases: Node.js version EOL notifications

[ejizba]

We sent a notification email in June 2023 which told customers that they should move from Node.js 14 or 16 to Node.js 18 by June 30, 2024 (docs here). The most common reasons I saw for filing a support case were:

• How to upgrade
• How to get the list of Node.js apps using v14 or v16
• Concern because they didn't think they had any Node.js apps

Support cases from June 2023 - Sept 2023
