Fix the PR checks for wazuh-ansible repository

[teddytpc1]

Description

As part of the DevOps overhaul objective, we need to fix the PR checks and adapt them to start using the Allocator module.

Currently, we have these checks that are using the machulav/ec2-github-runner@v2 module, and we have to use the Allocator module instead:

• https://github.com/wazuh/wazuh-ansible/tree/master/.github/workflows

Tasks

• [x] Modify the workflows to use the Allocator module
• [x] Test them
• [x] Provide evidence they are working properly

Examples/references

The following workflows use the Allocator, we should replicate its use:

• https://github.com/wazuh/wazuh-installation-assistant/blob/main/.github/workflows/Test_installation_assistant.yml
• https://github.com/wazuh/wazuh-installation-assistant/blob/main/.github/workflows/Test_installation_assistant_distributed.yml

Description

In the process of improving and correcting the PR checks for the wazuh-ansible repository, it was decided to maintain and improve the AIO (single instance) deployment but combining in the same workflow the deployment of all OS (CentOS_8, AmazonLinux_2, Ubuntu_22, RHEL8) by means of a matrix-type strategy

On the other hand, analogous to the AIO deployment, it was decided to keep the deployment of a distributed environment (composed of six instances) for each OS in the same combined workflow.
