Function is_metadata_route_file

pub fn is_metadata_route_file(
    app_dir_relative_path: &str,
    page_extensions: &[RcStr],
    with_extension: bool,
) -> bool

When you only pass the file extension as [], it will only match the static convention files e.g. /robots.txt, /sitemap.xml, /favicon.ico, /manifest.json.

When you pass the file extension as ['js', 'jsx', 'ts', 'tsx'], it will also match the dynamic convention files e.g. /robots.js, /sitemap.tsx, /favicon.jsx, /manifest.ts.

When withExtension is false, it will match the static convention files without the extension, by default it’s true e.g. /robots, /sitemap, /favicon, /manifest, use to match dynamic API routes like app/robots.ts.
