Description

This issue's objective is to fix a typo in Wazuh Installation Assistant.
The typo is on the variable wazuh_install_vesion and it's fixed to be wazuh_install_version.
This variable is used on the installMain.sh file in the case the Installation Assistant is run with the -V option.

I made a test with the changes and the output is the following:
