remove group-by from promql alert spec

[OrNovo]

Remove group-by array from promql-alert spec since when filling group-by through the query (e.g.

searchQuery: |-
     sum(
      max_over_time(aws_autoscaling_group_in_service_instances_average[15m] offset 30m) 
      / 
      aws_autoscaling_group_total_instances_average offset 30m
     ) **by (auto_scaling_group_name, region, cluster, env)**

), the alerts-API returns the group-by in the designated field as well (

groupBy: [auto_scaling_group_name, region, cluster, env]

), which causes a diff between the spec and the status and an attempt to update the CR forever.
