fix(tests): use valid list operators in Falco rule exception tests

[rosenbloomb-sysdig]

Summary

Fixed TestRuleFalcoWithExceptions to comply with stricter validator enforcement of list field operators.

Problem

The test was failing with validation error:

filter error: '=' operator not supported list filters.
Location: rule: TERRAFORM TEST ... - Attach to cluster-admin Role

This was caused by recent deployment of stricter validators that enforce the use of compatible operators for list fields. List fields (like ka.req.binding.subjects) must use compatible operators (in, exists, intersects) rather than the = operator.

Solution

1. Removed subjects_equal exception that used = operator with the list field ka.req.binding.subjects
2. Added explicit comps = ["in"] to only_one_field_without_comps exception to prevent it from defaulting to the = operator

Test plan

• Test passes locally with staging environment
• Test validated with Falco agent 14.4.0

Fixes validation errors without any breaking changes to the actual provider functionality.

Pull request overview

This PR fixes test validation errors in TestRuleFalcoWithExceptions by updating exception definitions to comply with stricter Falco rule validation that enforces compatible operators for list fields. The changes address a validation error where the = operator was incorrectly used with list-type fields like ka.req.binding.subjects, which require operators like in, exists, or intersects.

Changes:

• Removed the subjects_equal exception that used the incompatible = operator with the list field ka.req.binding.subjects
• Added explicit comps = ["in"] to the only_one_field_without_comps exception to prevent defaulting to the = operator

This is currently detecting a breaking change in the API. I would like to leave it on hold until we determine that it's OK to break this for current customers that may be using it, or we rollback and support previous behavior in the API.
