 * Sets `error.stack = stack`.

 *
 * @example
 * ```js
 * const error = new Error('one')
 * console.log(error.stack) // 'Error: one ...'
 * console.log(error.message) // 'one'
 *
 * setErrorStack(error, error.stack.replace('one', 'two'))
 * console.log(error.stack) // 'Error: two ...'
 * console.log(error.message) // 'two'
 * ```
