[BUG] Trigger not producing alert when query is specified

[uroskarama]

What is the bug?
When creating a Per Document monitor, and adding a Trigger with the query specified, the trigger is not triggered (Alerts are not produced).

How can one reproduce the bug?
Steps to reproduce the behavior:

1. Create a monitor with a query named query1.
2. Add new trigger to monitor, and in Trigger conditions dropdown select query1.
3. In Dev tools insert a document that matches query1.
4. Check Document findings for the monitor - document is found, but alert is not created.

What is the expected behavior?
Alerts are supposed to be produced by the trigger when query is set as condition.

What is your host/environment?
Opensearch Cluster Version - 2.4.0
Opensearch Dashboard Version - 2.4.0

Do you have any screenshots?

Do you have any additional context?
First screenshot is the suspected issue - for some reason the query is negated "!query[name=testq]"/
Second is the suggested fix for the issue in the code.

Were findings created, but not alerts? When choosing the dropdown for the trigger, was it specified to do a not of query, testq?
