Failed to run on Keycloak greater than v22

[leoraba]

Getting error loading keycloak-apikeys-1.0.1.jar extension on Keycloak greater than version 22.
Error found on Keycloak v23 and v24
Latest working version is v22.

Steps to reproduce the issue:

1. Copy apiKey extension onto Keycloak container:
   docker cp keycloak-apikeys-1.0.1.jar [CONTAINERID]:/opt/bitnami/keycloak/providers/
2. Restart Keycloak container.
3. Check Keycloak container logs
   EXPECTED: Keycloak container should run successfully with apikey extension loaded
   CURRENT BEHAVIOUR: Keycloak container fails to restart with the following error:

Based on Keycloak release v23,
TL;DR Keycloak has switched from quarkus-resteasy to RESTEasy Reactive. SPI's with quarkus-resteasy are not compatible on V23.

This requires a code change to migrate SPIs to use RESTEasy Reactive
