 Give you the possibility to set the locale for the mock generation. It is used by faker, see the list of available options [here](https://fakerjs.dev/guide/localization.html#available-locales). It should also be strongly typed using `defineConfig`.

+Type: `Boolean`

+Default Value: `false`.

+Example:
+
+```js
+module.exports = {
+  petstore: {
+    output: {
+      mode: 'tags-split',
+      mock: {
+        indexMockFiles: true,
