sourceType 'module' is not supported when ecmaVersion < 2015

Hey 👋

I for the love of god can't understand what's this error. Even the simplest config gives it:

import js from '@eslint/js'
import eslintPluginImportX from 'eslint-plugin-import-x'

export default [
  js.configs.recommended,
  eslintPluginImportX.flatConfigs.recommended,
  {
    rules: {
      'comma-dangle': ['error', 'never'],
      'semi': ['error', 'never']
    }
  }
]

I've tried different setting configurations and language options with no luck.

node - 22.10.0
eslint - 9.15.0
eslint-plugin-import-x - 4.4.2

reproduction - https://github.com/vladshcherbin/eslint-import
script - pnpm lint or pnpm eslint

@vladshcherbin I will look into this! I suspect #181 is related.
