🚀 Feature: Also show packages that need subscribers

[JoshuaKGoldberg]

Bug Report Checklist

• I have tried restarting my IDE and the issue persists.
• I have pulled the latest main branch of the repository.
• I have searched for related issues and found none that matched my issue.

Overview

Right now, the site only shows a user's packages whose monetary estimates are >$0 or are funded. That excludes packages that Tidelift knows about but don't yet have enough subscribers to provide income.

For example, lottie-react-native:

• Does not show up on https://tidelift-me-up-site.vercel.app/?username=ljharb&since=2001-01-01&author=on&maintainer=on&publisher=on
• Is shown in https://tidelift.com/lifter/search/npm/lottie-react-native right now as "Needs subscribers"

Let's add those into the list!

Additional Info

This is blocked on the tidelift-me-up library supporting these needs-subscriber packages: JoshuaKGoldberg/tidelift-me-up#255.
