fix(typescript-estree): don't infer single-run when --fix is in proces.argv

[JoshuaKGoldberg]

PR Checklist

• Addresses an existing open issue: works around Bug: single run mode breaks with fixers #9344
• That issue was marked as accepting prs
• Steps in Contributing were taken

Overview

Does a straightforward check for '--fix' in process.argv.

I'd have loved to use something more ... not-hacky, i.e. some explicit indication from ESLint itself. But our old friend eslint/rfcs#102 was rejected.
