Missing step in Wazuh Docker deployment section

[sydbarrett74]

On this page in Step 2, where one is asked to run this command—docker-compose -f generate-indexer-certs.yml run --rm generator—there is a missing thing one has to do beforehand. The wazuh_indexer_ssl_certs directory has to be created under ./config prior to issuing the command. If not, the command will fail.
