Issue with the LOCALE verification when run in --check mode

[erwangranger]

Opening this issue to further document the rationale for a recent change.

a colleague pointed out the following issue:

[cloud-user@myserver pre-install-playbook]$ ansible-playbook -i pre-install.inventory.ini viya_pre_install_playbook.yml --tags locale_check --check

PLAY [sas-all] *****************************************************************************************************************************************************************************

        to retry, use: --limit @/home/cloud-user/viya-ark/playbooks/pre-install-playbook/viya_pre_install_playbook.retry

However, when running without the --check flag, it works fine

[cloud-user@myserver pre-install-playbook]$ ansible-playbook -i pre-install.inventory.ini viya_pre_install_playbook.yml --tags locale_check
