Dynamic user names on dss_google_voice_v2.0

[luci-11]

Hi,
I cannot open pull request but I think it could be useful to have dynamic strings instead of hard coded names in "DSS VOICE Benvenuto userX" automations .
When using person as dss_dispositivi_user1 (for example) you can use the following message code:

      - service: input_boolean.turn_off
        entity_id: input_boolean.dss_voice_user1_appena_entrato
      - service: script.dss_voice_riproduci_messaggio
        data_template:
          message: >-
            {% set user = state_attr('group.dss_dispositivi_user1', 'entity_id')[0] %}
            {% set nome = state_attr(user, 'friendly_name') %}
            {{ [
            "Bentornato "+ nome+"... " ,
            "Ciao "+ nome +"... " 
            ] | random }}
