fix: ignore post_logout_redirect_uris when logout is disabled

[manvydasu]

Hello, I think there is a slight problem wtih rpInitiatedLogout configuration.

inside the client_schema.js there is this check at line 79

  if (features.rpInitiatedLogout.enabled) {
    RECOGNIZED_METADATA.push('post_logout_redirect_uris');
  }

However, it looks like it does nothing, because post_logout_redirect_uris is already included in the default RECOGNIZED_METADATA array. In order for flag features.rpInitiatedLogout.enabled to properly work, default recognized metadata properties should be changed.

I can't run tests locally due to structuredClone error, so haven't verified yet if tests don't break.
