Disable inlay hints for tests (or allow conditional overrides)

Suggestion

Originally opened at https://github.com/microsoft/vscode/issues/132304 - they asked me to file upstream.

inlay hints

✅ Viability Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

⭐ Suggestion

I ❤️ the new inlay hints feature. One area where it's a bit noisy is in tests, though. Even with the literals setting, it shows up for Jest (and similar) test blocks (describe, it, test). Please consider adding a way to override this for certain cases. Thank you!

📃 Motivating Example

As a developer, I want to maximize readability while minimizing noise.

💻 Use Cases

• VSCode

The issue names no files, tests, or entry points. Start by locating the TypeScript and JavaScript inlay-hints implementation, then review the linked VSCode context and TypeScript design goals. Done means supporting suppression or conditional overrides for test blocks such as describe, it, and test.
