[Security Solution][Detections] Update telemetry to use ML contract (#71665)

* Update security solution telemetry to use ML providers

This interface recently changed and we're now able to use the ML
contract to retrieve these values. A few unnecessary arguments are
stubbed as we're in a non-user, non-request context.

* Simplify our capabilities stub assignment

This is more legible but still gets the point across; the intermediate
variable was explicit but ultimately unnnecessary.

* Update tests following telemetry refactor

We're not calling different methods, so our mocks need to change
slightly.
