Yes, it always returns a string, but since I didn't know for sure if packageJSONUrl is a URL, in the old code we had validations but in this one I needed to make this validation explicit.

Hey, I'm sorry but a lot of commit landed on the staging branch since you opened this backport and now it has conflicts.

src,lib: reducing C++ calls of esm legacy main resolve
f260c35 
Instead of many C++ calls, now we make only one C++ call
to return a enum number that represents the selected state.

@targos It's okay to include #48664 in this PR since they should land together?

@nodejs/lts / @nodejs/releasers Now that Node.js 18 is in maintenance I think the risks of this backport PR outweigh potential benefits. Thoughts?

+1, I don't think we should be landing performance improvement backports in a maintenance release line

I agree, this improvement helps but is not that significant that worth the risk.
