Defaulted --comment globs to --typescript settings

PR Checklist

• Addresses an existing issue: fixes Allow tsconfig files and --typescript to inform --comment #426
• That issue was marked as status: accepting prs

Overview

If --comments is provided as true from having no globs passed to it, we'll now default to a configuration provided by --typescript if available. That necessitates passing in a found TypeScript configuration to convertComments.

Uses minimatch (already a transitive runtime dependency) to emulate TypeScript's exclude, files, and include.

LGTM 🚀 But I think it should support specifying a custom tsconfig file path as some projects would use a different path or inherit from a base option which is not fully complete (like monorepos or Angular ones).

YES! Excellent idea, will file a followup issue! 👏
