can't access /keystatic route with Astro i18n integration and prefixDefaultLocale: true

Hi, I'm setting up keystatic in a localized project where the first segment of my url is the language locale.

my-domain.com/en/......
mydomain.com/es/.....

I'm not able to enter the keystatic panel because the localhost:4321/keystatic is matched by the src/pages/[lang] route.

I actually found the place where this configured and I added the /en prefix to make it work changing directly the file in my node_modules folder.

ui pattern
api pattern

injectRoute({
          // @ts-ignore
          entryPoint: '@keystatic/astro/internal/keystatic-astro-page.astro',
          entrypoint: '@keystatic/astro/internal/keystatic-astro-page.astro',
          pattern: '/en/keystatic/[...params]',
          prerender: false
        });
        injectRoute({
          // @ts-ignore
          entryPoint: '@keystatic/astro/internal/keystatic-api.js',
          entrypoint: '@keystatic/astro/internal/keystatic-api.js',
          pattern: '/en/api/keystatic/[...params]',
          prerender: false
        });

is there a way to set this up through normal config? I think it could be a useful feature

Start in packages/astro/src/index.ts, especially the UI and API route patterns linked in the issue, and reproduce the setup with an Astro src/pages/[lang] route and prefixDefaultLocale enabled. Check how the generated /keystatic and /api/keystatic routes are matched; done means localized projects can configure the locale prefix without editing node_modules and the Keystatic panel and API remain reachable.
