fix: fix authHeader without cookie-parser middleware

[express-openapi-validator v5.8.3][1] and
00d070b (fix: add cookie support for HTTP bearer authentication (cdimascio#949), 2024-10-27)
breaks HTTP bearer authentication when the `cookie-parser` middleware
is not present (and therefore `req.cookies` is not present).
