Description

The aim of this PR is to fix the output generated in the certificate generation using the Wazuh certificates tool. The bug consisted in showing generated certificates when they were not created.

Tests

1. 🟢 Testing the reported case:

root@ubuntu221:/home/vagrant# cat config.yml 
nodes:
  # Wazuh indexer nodes
  indexer:
    - name: node-1
      ip: "192.168.56.44"

root@ubuntu221:/home/vagrant# bash wazuh-certs-tool.sh -A
23/02/2024 12:50:27 INFO: Generating the root certificate.
23/02/2024 12:50:27 INFO: Generating Admin certificates.
23/02/2024 12:50:28 INFO: Admin certificates created.
23/02/2024 12:50:28 INFO: Generating Wazuh indexer certificates.
23/02/2024 12:50:28 INFO: Wazuh indexer certificates created.

root@ubuntu221:/home/vagrant# ls wazuh-certificates/
admin-key.pem  admin.pem  node-1-key.pem  node-1.pem  root-ca.key  root-ca.pem
root@ubuntu221:/home/vagrant# 

Only the indexer certificates are created and the output confirms it.
