NextDrupalBase.addLocalePrefix() fails when path starts with same letters as the locale

next-drupal (NPM package)

Describe the bug

In next-drupal version 2.0.0, the NextDrupalBase.addLocalePrefix() fails to add a proper locale prefix if the given path starts with the same letters as the locale. This affects the results from NextDrupalPages.translatePathFromContext() among others.

Expected behavior and steps to reproduce:

Expected value for test would be /en/enable/testing, but /enable/testing is returned instead:

import { NextDrupal } from "next-drupal"

const drupal = new NextDrupal("https://example.com")
const test = drupal.addLocalePrefix('/enable/testing/', {
  locale: 'en',
  default_locale: 'fi'
})

Additional context

I believe the issue comes from this condition:

if (locale && !path.startsWith(`/${locale}`) && locale !== defaultLocale) {
  localePrefix = `/${locale}`
}

Maybe replacing startsWith(`/${locale}`) with startsWith(`/${locale}/`) would do the trick?
