Change dev_dependencies to any

Using path dependencies here is misleading - they are not sufficient for a
`pub get` and we do not expect to do a pub solve in this package. In order to
suppress the warnings on `pub publish` we need only the `any` dependencies and
can rely on the repo's `.packages` file to resolve their path.
