issues with plugin for Keycloak v21

Bug

Related to #35 (closed)

Description

Describe the problem, what were you doing when you noticed the bug?

• We have been continuing to upgrade our BigBang version.
• BB 1.57.x introduces Keycloak major version 21.
• This change requires a corresponding update to the plugin (this repo).
• We tried both 3.2.0 and 3.2.1.
  • 3.2.0 fails to require terms and conditions to be agreed upon login (this bug was fixed in 3.2.1)
  • 3.2.1 fails whenever a user tries to login with an internal 500 server error complaining about "no such methods". Presumably, this is caused by the quarkus changes introduced in plugin v3.2.1 since we do not get this error in 3.2.0
• Not having a functional plugin version requires us to manually fix the terms and conditions bug in a submodule of this repo @3.2.0 since 3.2.1 is in an unusable state.

Provide any steps possible used to reproduce the error (ideally in an isolated fashion).

• Use plugin 3.2.0 with Keycloak v21
• Use plugin 3.2.1 with Keycloak v21
• Neither of these versions work
