Complementary PR of #2801.

The aim of this PR is to silence the output of the sudo packages check. I noticed that, when the sudo package is installed, the output of the command -v command is displayed in the prompt.

root@ubuntu22:/home/vagrant# bash wazuh-install.sh -g -v
01/02/2024 12:07:58 DEBUG: Checking root permissions.
01/02/2024 12:07:58 DEBUG: Checking sudo package.
/usr/bin/sudo
01/02/2024 12:07:58 INFO: Starting Wazuh installation assistant. Wazuh version: 4.8.0

With this change, the output is the following:

root@ubuntu22:/home/vagrant# bash wazuh-install.sh -g -v
01/02/2024 15:31:52 DEBUG: Checking root permissions.
