Zabbix Agent 2: Version 7 is available for 3 month by now - time for an upgrade?

[ThomasBahn]

@pschmitt Thank you for providing the Home Assistant add-on for the Zabbix agents.

On June 4th Zabbix version 7 was released and got three minor updates since than.

I think, it's time for an update of the add-on to use zabbix-agent2:alpine-7.0-latest instead of 6.4, which had "End of Full Support" on June 30th, 2024 (see https://www.zabbix.com/life_cycle_and_release_policy).

7.0 is a LTS version with "End of Full Support" on June 30th, 2027, making this change quite sustainable.

What do you think?
