Valid Canary runtime versions are outdated

[theofilospan]

Hello,

The current Canary runtime versions are outdated. Under troposphere/validators/synthetics.py the valid versions are the following: ["syn-nodejs-2.0", "syn-nodejs-2.0-beta", "syn-1.0"] The versions syn-nodejs-puppeteer-3.5 to syn-nodejs-puppeteer-3.9 were deprecated on January 8, 2024. (Source)

The current valid versions are the following:

• syn-nodejs-puppeteer-4.0
• syn-nodejs-puppeteer-5.0
• syn-nodejs-puppeteer-5.1
• syn-nodejs-puppeteer-6.0
• syn-nodejs-puppeteer-6.1

Let's add them to the valid canary runtime versions and replace the old ones.
