As wordpress is deployed by Ansible, we also have an 'ad-hoc' ansible task to rollout upgrades.
To do this, it's using the wp_release ansible variable, that corresponds to the wordpress version to download and unarchive.
If you need to update the deployed plugins, update also in ansible inventory the wp_plugins list to reflect new versions of the plugins to be updated.
We want to first validate a successful upgrade on the dev instance, available on https://blog.dev.centos.org and then proceed with the prod one later.
PS: you need administrator right to then be able to visit the /wp-admin/update-core.php
So edit the ansible inventory/host_vars section with new value and then launch the ad-hoc task:

Once it's done, just ensure to visit <url>/wp-admin/update-core.php and then verify the results.
If it's all working fine, you can then proceed with the prod instance.
