The default version of packages is very old and not available in repos anymore. We bump it up to the latest so the formula works out of the box.

Please check failed jobs in pipeline. Particularly you need to fix your commit messages, more about it here https://github.com/saltstack-formulas/.github/blob/master/CONTRIBUTING.rst

I still think default version must be LTS release - https://www.zabbix.com/life_cycle_and_release_policy

Also please check #123 for some thoughts about change of the default version. Especially as I already mentioned here

On the other hand, it's also required to update configuration templates, for agent, server and proxy, and that's a much bigger deal.

Moreover this formula ships it's own SQL files for MySQL, and if you want to update default version, you also need to provide SQL file for that version.
Some info about creating SQL file can be found here #104
This part must be updated too to support new version

zabbix-formula/zabbix/mysql/schema.sls

Lines 18 to 25 in e3f777d

	{% if zabbix.version_repo|float < 3 -%}
	{% set db_version = '22' -%}
	{% elif zabbix.version_repo|float < 3.4 -%}
	{% set db_version = '30' -%}
	{% else -%}
	{% set db_version = '34' -%}
	{% endif -%}
	{% set sql_file = settings.get('sql_file', '/usr/share/zabbix-server-mysql/salt-provided-create-' ~ db_version ~ '.sql') -%}

So changing of the default version isn't that easy as one can thought at first glance.
