Netlify Adapter _redirects overwriting blanket redirect to render function

[saturnonearth]

Describe the bug

Bug was introduced in recent Edge Function updates (even when not using the feature).

I had a _redirect file that had one line,

http://example.com/* https://example.com/:splat 301!

This was to fix that the fact that HTTP was not correctly being redirected to HTTPS by Netlify on first load on a fresh cache.

When building with new @next.55, my _redirect file is being copied over, but it is not including the necessary * /.netlify/functions/render 200, which seems to be needed to render the entire app. It seems to work correctly if you have no pre-existing _redirect file.

Reproduction

Add _redirect file to Static folder, and cry as your app is put into the magicians hat.
