fix: disable jsonc/comma-dangle

[JoshuaKGoldberg]

PR Checklist

• Addresses an existing open issue: fixes 🛠 Tooling: Create end-to-end test failures on main: trailing commas in tsconfig.json #1257
• That issue was marked as status: accepting prs
• Steps in CONTRIBUTING.md were taken

Overview

Disables the jsonc/comma-dangle rule altogether so as to not conflict with Prettier. I suppose if any tool doesn't support trailing commas in a file, it'll report that directly. And most tools generally support jsonc anyway. 🤷
