Describe the Bug

Below, I have it set up to redirect from /foo or /foo/ to /bar.
However, when I build this with the Cloudflare adapter, the trailing slash is removed in the _redirects file, and accessing /foo/ results in a 404.

// astro.config.mjs

export default defineConfig({
  redirects: {
    '/foo': '/bar',
    '/foo/': '/bar',
  },

  output: 'server',
  adapter: cloudflare(),
});

# dist/_redirects

/foo    /bar    301
/foo    /bar    301

What's the expected result?

The trailing slash has not been removed from the _redirects file, so it is expected that accessing /foo/ will result in a successful redirect.

# dist/_redirects

/foo    /bar    301
/foo/    /bar    301

Having the same issue.
My workaround: Create a custom _redirects file in /public directory with correct redirects.
But indeed, a built-in solution would be nicer here.
@ astro team: Do you agree? Would you accept a PR for that?

I think a PR is welcome. However this needs to be fixed in the underscore redirects package inside the core repository, I guess.
