valuelookupDependency

Does a case-sensitive search by package name and a range of versions.

We get back any number of versions of the specified package name, all satisfying the version range constraint.

Additionally, `preferred-versions` (such as version deprecation) are honoured in this lookup, which is the only difference to lookupDependency

valuelookupPackageName

Does a case-sensitive search by package name.

Additionally, `preferred-versions` (such as version deprecation) are honoured in this lookup, which is the only difference to lookupPackageName
