eslint 9.22 introduced the helper function defineConfig (see https://eslint.org/blog/2025/03/flat-config-extends-define-config-global-ignores/#introducing-defineconfig()-for-eslint for more information).

As vuejs/eslint-config-typescript also provides its own helper function defineConfigWithVueTs, I wonder whether this is still necessary.
If so, the implementation of defineConfigWithVueTs should be refactored to use the eslint helper function. (e.g. flattening can be done by eslint helper function).
