deps [NET-1401]: update to Node.js 22

[harbu]

Summary

Update Node.js to active LTS version 22. As per custom we maintain backwards compatibility (somewhat) to previous LTS 20.

In practice this means that

• We prefer v22 and use it for the Docker image and .nvmrc
• We still support v20 therefore we have it set for Node v20 types and tsconfig base ("lowest common denominator")

Future improvements

• Update dependencies and replace request package with something else in autocertifier packages to get rid of punycode transitive dependency and the deprecation warning. (See NET-1409 and NET-1404 for more information)

Checklist before requesting a review

• Is this a breaking change? If it is, be clear in summary.
• Read through code myself one more time.
• Make sure any and all TODO comments left behind are meant to be left in.
• Has reasonable passing test coverage?
• Updated changelog if applicable.
• Updated documentation if applicable.

Maybe the PR description would be even more explicit about there current approach:

• we prefer v22, therefore we use v22 for the Docker image and .nvmrc
• we require v20, therefore we use Node v20 types and tsconfig base
