fix(eslint-plugin): Skip missing 'rest' tuple type arguments in no-misused-promises

Fixes #5807

Overview

When linting a function with a 'rest' tuple argument, we might have different numbers of arguments between signatures:

function foo(...args: []);
function foo(...args: [string]);

This PR makes no-misused-promises handle this code correctly, by ensuring that we only check an argument when we have a corresponding type parameter in the tuple type arguments.
