Repro

{
  "rules": {
    "@typescript-eslint/no-floating-promises": "error"
  }
}

(async () => {
	await something();
})();

Expected Result

I expected it not to report as it's an intentional action. It doesn't catch a mistake.

If you're not willing to add this exception by default, at least add an option to ignore async IIFEs.

Actual Result

It reports as a floating promise, which is technically correct, but not wanted behavior, at least from my perspective.
