[Infrastructure UI] Fix time range filter in alerts query

[tonyghiani]

📓 Summary

Closes #153741

This PR fixes the time range filter by using the kibana.alert.time_range field instead of @timestamp.

🧪 Testing

• Navigate to Hosts View
• Create an Inventory Alert that will trigger immediately
• Refresh the search until some alerts are triggered
• Play with relative time range (eg. 15 min ago -> 2 min ago) to verify alerts appears correctly

Added the backport to 8.7 by mistake, the related feature is introduced in 8.8 so backporting is not necessary.
