feat(git-validator): count for the expression of top-level-await

[zanminkian]

In node22, require can import esm module (experimental). I don't like this feature honestly . I think cjs should go to the dust bin. We shuold not save cjs (require) any more.

Way 1: We may ban top-level-await.
Way 2: Just like eslint-plugin-top do, disallow top level side effects.

Js is a script, using statement on top level is not a good practice.

for(let i = 0; i < 100; i++) {
  // doing stuff
}

export const foo = xx;
