Ansible installation documentation update

[adavinchi]

The Wazuh documentation for installation via Ansible is not very clear and there are steps that can be improved.

1. The Windows endpoints subsection is not consistent with similar subsections making it seem like it is a different step rather than an optional step
2. The Remote Connection section includes the command cat ~/.ssh/id_rsa.pub | ssh centos@192.168.33.31 "cat >> ~/.ssh/authorized_keys" this command fails because the Ansible server does not yet have access to the remote server. this steps is supposed to created the access. It also does not clearly state that some values are placeholders that should be replaced eg centos
3. The guide does not clearly separate all-in-one installation from cluster installation.
4. The cluster installation section does not clearly guide the user on how to modify the /etc/ansible/roles/wazuh-ansible/playbooks/wazuh-production-ready.yml file
