main/nodejs: outdated version in v3.16 release (missing security patches)
The latest version in package repository is 16.20.1-r0: https://pkgs.alpinelinux.org/package/v3.16/main/x86_64/nodejs
On August 9th, 2023, Node released v16.20.2: https://nodejs.org/en/blog/release/v16.20.2 ; this release contains fixes for several CVEs.
According to https://www.alpinelinux.org/releases/ , Alpine v3.16 is still in support (end of support: 2024-05-23) at "security fixes" support level, so it seems that nodejs v16.20.2 should be in the package repository.
