keycloak_realm: fix change detection in check mode by normalizing realms beforehand

[fgruenbauer]

SUMMARY

The lists enabledEventTypes, otpSupportedApplications and supportedLocales are sorted (in the normalize function) for the diff but not when comparing realms for the changed parameter. So the module always detects a change in check mode but shows an empty diff:

TASK [kc1 - realm-1 - Update Keycloak realm] ************************************************************************************************************************************************************************
changed: [kc1]

To minimize the changes, the lists should be sorted before comparing the realms as well.

ISSUE TYPE

• Bugfix Pull Request

COMPONENT NAME

keycloak_realm

ADDITIONAL INFORMATION

1. create minimal realm:

- name: Create or update Keycloak realm (minimal example)
  community.general.keycloak_realm:
    auth_client_id: admin-cli
    auth_keycloak_url: ...
    auth_realm: master
    auth_username: ...
    auth_password: ...
    id: realm-1
    realm: realm-1
    state: present
    enabledEventTypes:
    - AUTHREQID_TO_TOKEN
    - AUTHREQID_TO_TOKEN_ERROR
    - CLIENT_DELETE
    - CLIENT_DELETE_ERROR

2. subsequent check runs always detect a change but show an empty diff
