fix(remix): Ensure headers with the same name do not get overwritten

[BRKalow]

Description

When authenticating a request, it's possible we may pass multiple headers with the same name (e.g. multiple Set-Cookie headers). By using headers.set(), we were only accepting the last header of that name. Switching to headers.append() should fix this.
