This fixes our `basePath` detection/replacing server-side as we were incorrectly considering `/docss` a match for a `basePath` of `/docs` which caused us to have an unexpected value in the `normalizeLocalePath` function. - Fixes #22429 - Regression introduced in #17757 - Fixes: https://github.com/vercel/next.js/issues/31423 Co-authored-by: JJ Kasper <22380829+ijjk@users.noreply.github.com>
