react-instantsearch-router-nextjs wrong replace url on push

🐛 Current behavior

the fix on push method work on all the url, even on the domain part and not only on the path

    push(newUrl) {
      let url = newUrl
      // We need to do this because there's an error when using i18n on the root path
      // it says for example `pages/fr.js` doesn't exist
      if (singletonRouter.locale) {
        url = url.replace(`/${singletonRouter.locale}`, '');
      }

      // No need to provide the second argument, Next.js will know what to do
      singletonRouter.push(url, undefined, {
        shallow: true,
      })
    },

if the url is something like https://it.mydomain.eu/product with the locale part in third level domain, it will replace the url to https://.mydomain.eu/product

🔍 Steps to reproduce

Live reproduction

💭 Expected behavior

should only replace the path part

Possibile Solution

you can try with a regex like this: https://regex101.com/r/U8mzbj/1

    push(newUrl) {
      let url = newUrl
      // We need to do this because there's an error when using i18n on the root path
      // it says for example `pages/fr.js` doesn't exist
      if (singletonRouter.locale) {
        url = url.replace(new RegExp(`(?<=^https?:\/\/[^\/]+)\/${singletonRouter.locale}(?=\/|$)`, 'i'), '');
      }

      // No need to provide the second argument, Next.js will know what to do
      singletonRouter.push(url, undefined, {
        shallow: true,
      })
    },
