Poem OpenAPI Cookie SecurityScheme ignores provided key_name

[lewisrb]

Expected Behavior

When a key_name is provided for a given cookie SecurityScheme, then the session token should be returned in the cookie with the provided name.
E.g.
The below should result in a cookie named session being populated with the expected session token.

#[derive(SecurityScheme)]
#[oai(ty = "api_key", key_in = "cookie", key_name = "session")]
struct CookieAuth(ApiKey);

Actual Behavior

The session token is always returned in the cookie poem-session.

Steps to Reproduce the Problem

1. Use a cookie-based SecurityScheme with a provided key_name.
2. Authenticate with a login/auth endpoint.
3. Observe returned cookies.
