why 18? not 20?

Just never try that. Do you think we can use lts/iron?

I’m not sure, but the PR say "with LTS version"

by now the LTS is 20

[Asuka109]

@arvinxx Node.js 18 is one of the lts versions and will be supported as a long-term version until April 2025.

It appears you're not very experienced with using version 20 either. How about setting it to 18 for now?
