Cors AllowWildcard never set - Wildcard origins not taken into account

[YassineElbouchaibi]

router v0.92.3

Description

Using only a config.yaml to setup the router, it is impossible to make use of wildcards in cors.allow_origins as AllowWildcard is never set and therefore parseWildcardRules() doesn't pickup any rules.

Steps to Reproduce

Start a router with the following in the config:

cors:
  allow_origins: [http://*]
  allow_headers: ["*"]
  allow_credentials: true

Use chrome to make a fetch request to your router and you will get 403 Forbidden in the OPTIONS request.

Expected Result

OPTIONS request should go through

Actual Result

403 Forbidden in the OPTIONS request

• allow_wildcard should be added here ? https://github.com/wundergraph/cosmo/blob/main/router/pkg/config/config.go#L112
• AllowWildcard is never set anywhere (Except in tests where its manually set to true) https://github.com/search?q=repo%3Awundergraph%2Fcosmo+AllowWildcard&type=code
