Repro Code

class Foo<T> {
  value: T
}

class Bar<T> {
  foo = Foo<T>
}

new Bar()

ESLint Config

module.exports = {
  "rules": {
    "@typescript-eslint/no-unused-vars": ["error"]
  }
}

tsconfig

{
  "compilerOptions": {
    "strictNullChecks": true
  }
}

Expected Result

To pick up that T in foo = Foo<T> is being used.

Actual Result

'T' is defined but never used. 5:11 - 5:12

Additional Info

The ability to modify function references with generics is a new feature in TS 4.7, so this is probably the reason the rule hasn't updated yet to support it.
