chore: Fix flags and add tests

this test is fine but i think we need a destructive test. I've found if a target lacks a dep in the tests stanza or a minSupported it fails to parse versions for a package.json

This is what I did to verify the destructive path

Yes, this is an original design decision. When we can't find a version, we assume the whole manifest is broken and bail on it:

newrelic-node-versions/parse-package.go

Lines 36 to 52 in 023ae85

	if target.MinSupported == "" {
	version, err := findMinimumSupported(target, pkg.Tests)
	if err != nil {
	return nil, err
	}
	lastVersion = version
	} else {
	version, err := semver.NewRange([]byte(target.MinSupported))
	if err != nil {
	return nil, fmt.Errorf("%s: could not parse minSupported string '%s'", pkg.Name, target.MinSupported)
	}
	lastVersion = &version
	}
	if lastVersion == nil {
	return nil, fmt.Errorf("%s: %w", pkg.Name, ErrTargetMissing)
	}

I'd say that changing that behavior is outside of the scope of this PR. It is a definite change in the way the tool works.

[bizob2828]

that's fair
