feat(lambda): NODEJS_LATEST now points to nodejs20.x

[MunchyYDL]

AWS CDK v2.107.0 introduced nodejs20.x as a valid runtime for lambda, including the NODEJS_20_X, but the NODEJS_LATEST static still uses nodejs18.x in the latest release (v2.110.1).

This PR just adjust NODEJS_LATEST to use nodejs20.x instead.

Closes #28125.

Thanks for helping out @kaizencc, I just haven't had the time to continue with this. :)
But as mentioned in the issue I opened for this, there is already some work being done on this issue, so I'm not sure that this will be merged, or maybe you are involved in that work?

#28125

[kaizencc]

Hi @MunchyYDL, I'm part of the CDK team and I'm unaware of any work being done on this besides you and me right here :). I'll get back to this PR today and hopefully fix the failing build, and then merge it to get you that sweet, sweet contribution!

[kaizencc]

Hi @MunchyYDL, so I created #28171 after talking to some folks on the team. tl;dr: is that we can't move forward here until node20 exists in all regions, which hasn't happened yet. I'm going to park this PR in draft mode, and when the time comes, revive it and get it in.
