[elastic_security] fix system test

[brijesh-elastic]

Proposed commit message

elastic_security: correct system test rule config to prevent updating
the fleet health status to degraded

Previously, the rules matched requests based on the presence of the current year in the request body.
This PR removes that dependency.
