fix(npm): reduce copy packages when resolving optional peer dependencies (#17280) 
If an optional peer dependency entry previously wasn't resolved and it's
now being resolved, then it will add it as if it were a dependency of
the previously resolved package instead of creating a new "copy package"
(seems to be what npm and pnpm does).

Closes #17240
