fix: allow void as statement in ts file

[zanminkian]

Description

// main.ts
/* eslint-disable @typescript-eslint/require-await */
async function test() {
  return 'test'
}

setTimeout(() => {
  void test()
})

export {}

Let's say I have code above. Run lint will cause no-void error. But after adding tsconfig.eslint.json file to project root, this error will disappear.

I think, adding tsconfig.eslint.json file to the root of project should bring more stricter rules to project. Deleting the tsconfig.eslint.json file should remove some stricter rules. But in the example above, deleting the tsconfig.eslint.json file will bring more stricter rule, which should not be.

If I want to make my project stricter, I will add tsconfig.eslint.json to the root of project. But I won't add it suddenly because this will cause too many error. I will fix my code first.

When fixing some async function, I have to add void before function, which is compatible for add tsconfig.eslint.json later, but will cause error right now.
