linter: no-unused-vars false positive w/TS overload

[eventualbuddha]

no-unused-vars warns on the following code:

export function log(message: string, ...interpolations: unknown[]): void;
export function log(message: string, ...interpolations: unknown[]): void {
  console.log(message, interpolations);
}

It claims interpolations in the overload signature is unused. However, it only makes sense to check for unused vars in functions with bodies. Here's the output:

❯ npx oxlint@latest test.ts

  ⚠ eslint(no-unused-vars): Variable 'interpolations' is declared but never used.
