fix: npm get peer deps returns list and not object when using range

[rbnayax]

Running the test without the fix results in:

AssertionError: expected { 'eslint-plugin-unused-imports': [ { eslint: '9', '@typescript-eslint/eslint-plugin': '8' }, { '@typescript-eslint/eslint-plugin': '^8.0.0-0', eslint: '^9.0.0' } ] } to deeply equal { 'eslint-plugin-unused-imports': { '@typescript-eslint/eslint-plugin': '^8.0.0-0', eslint: '^9.0.0' } }

getPeerDependenciesFromRegistry is currently typed to take an exact version (Version), not a version range (VersionSpec). They both resolve to string, so the type checker does not catch this yet.

Is there somewhere in the code that is calling getPeerDependenciesFromRegistry with a version range instead of an exact version? I think we need to fix it there. Getting the peer dependencies of an entire version range doesn't really make sense to me.

You are correct, but for the life of me, I can't remember how I came to find that "issue". I can't reproduce it locally and I can't see how version spec was passed here. So I will close this PR for now
