[JoshuaKGoldberg]

PR Checklist

• Addresses an existing open issue: fixes 📝 Documentation: File issues for remaining issue-less TODOs in code #1987
• That issue was marked as status: accepting prs
• Steps in CONTRIBUTING.md were taken

Overview

Cleans up some pending code TODOs:

• Bumping @vitest/eslint-plugin to include fix(valid-title): also allow string types with settings.typecheck vitest-dev/eslint-plugin-vitest#682
• Refactors retGitDefaults to execute a straightforward git remote get-url origin instead of the full git-remote-origin-url
• Uses sort-keys instead of the ad-hoc internal sortKeys
• Uses zod-package-json instead of a manually written schema

Otherwise doesn't change behavior, instead adding links to:

• 🛠 Tooling: Refactor readNpmDefaults to properly use Bingo Inputs #1990
• 🛠 Tooling: Figure out how to test email transforms #1991
• 🛠 Tooling: Figure out strategy with resolveBin #1992
