Bump Keycloak version to 24.0.4

[sberyozkin]

This upgrade is possible with thanks to @pedroigor suggesting to use a JSON file at the startup which allows Keycloak to avoid enforcing that an attribute like email is required during the new user registration or authentication.

🙈 The PR is closed and the preview is expired.

Sorry, I thought I tried most of the integration tests :-), will look at it tomorrow

It was just an error message that got changed in a negative test for the unsupported token exchange feature

@rsvoboda @gastaldi @gsmet afaiu, we need this in 3.8 to align with the supported version of Keycloak

This is fail of coordination between Keycloak and Quarkus. Such a big change should have been merged into main much sooner, https://github.com/keycloak/keycloak/releases/tag/24.0.0 was released Mar 4.

I don't like such a big change coming in without bake time.
