Potential Bug - localeStructure config not working

[sbue]

Describe the bug

I have changed the default value for localeStructure from {{lng}}/{{ns}} to be {{ns}}/{{lng}}. I find this neater for my use case (namespaces tend to be very long, I don't want to write them twice)

Here is my i18n.ts file

import NextI18Next from 'next-i18next'
import * as path from 'path'
import { I18NextContext } from '@/utils/types'

const NextI18NextInstance = new NextI18Next({
  defaultNS: `common`,
  defaultLanguage: `es`,
  localePath: path.resolve(`public/static/translations`),
  otherLanguages: [`en`],
  fallbackLng: `en`,
  localeStructure: `{{ns}}/{{lng}}`,
})

export const { appWithTranslation, withTranslation } = NextI18NextInstance

Here is the error I am getting

error - Error: Default namespace not found at /my-project/public/static/translations/es/common.json
    at createConfig (/my-project/node_modules/next-i18next/dist/commonjs/config/create-config.js:117:19)

Occurs in next-i18next version

7.0.1

Steps to reproduce

Use the same config as my own

Expected behaviour

I would have expected the default namespace to be as such: public/static/translations/common/es.json

Yep, looks like the logic here just needs to be updated to use localeStructure instead of /${defaultLanguage}/${combinedConfig.defaultNS}. PRs welcome!
