fix(docs): remove conflicting redirects and i18n config causing build failure (#2465)

In Astro 5 static build mode, config-level redirects with dynamic patterns
(e.g. /en/[...slug]) create redirect routes that Astro tries to statically
generate, but the redirect route handler has no getStaticPaths(), causing a
[GetStaticPathsRequired] build error.

The [locale]/[...slug].astro page already handles these redirects programmatically
via Astro.redirect(), so the config-level redirects were redundant and conflicting.
The i18n routing config was also creating injected fallback routes that clashed
with the manual locale routing in the page files.
