Description

in the light of 1246 I discovered default target is es2025 and it only es* targets are expected. underlying webpack does support node* as a target, but ncc restricts it. but using es version as a target doesn't make sense for nodejs versions, because es support is fragmented.

I'd like to relax es* only target restriction to include node* as well, to make GitHub Action build artifacts smaller by not transpiling everything to es2015 but rather only to what's missing in node20 for example

Contributor guide

Research direction
Start by examining the source code of ncc to locate where target validation occurs (likely in the webpack configuration). Look at issue #1246 for context on why targets matter. Check the existing allowed targets list and consider extending it to include node versions. Review any webpack documentation on node targets. The PR should update the validation to accept node versions and possibly adjust the default target based on environment.
