fix: support package.json bin objects

[JoshuaKGoldberg]

PR Checklist

• Addresses an existing open issue: fixes 🐛 Bug: "options.bin?.replace is not a function" when package.json bin is an object #2039
• That issue was marked as status: accepting prs
• Steps in CONTRIBUTING.md were taken

Overview

Updates the PartialPackageData type to note that bin could be a Record<string, string>, not just a string. blockPackageJson will collect its values if it is an object.

Also updates other references to options.bin to use a new getPrimaryBin function for determining what the main runner is. Per https://docs.npmjs.com/cli/v11/configuring-npm/package-json#bin using the same name as the repo is equivalent to using a string.
