Description
According to the test proposed in the RC issue:

Wazuh agent:

Installation: Wazuh WUI one-liner deploy FQDN GROUP (created beforehand)

we should be able to assign agents to a group when using the one-liner deployment method. This is not possible since the option to select group is not given

Steps to reproduce

1. Go to 'Agents'
2. Click on 'Add new agent'
3. See error
