Warning is outdated when the Cinemachine Composer Component is present without a Tracking Target Assigned

Steps to reproduce:

1. Open any Project with Cinemachine 3+ Installed
2. Add a "Cinemachine Rotation Composer" Component to any Game Object
3. Fix issues to add "Cinemachine Brain" and "Cinemachine Camera" to the Scene
4. Observe the Warning in the "Cinemachine Composer" Component

Actual results: Warning "A LookAt Target is required in the CinemachineCamera" is shown

Expected results: Warning should read "A Tracking Target is required in the CinemachineCamera" should be shown instead as this was changed with all the other Components that require a Tracking Target

Reproducible with versions:  3.1.4 (6000.4.0a2)

Tested on (OS): Windows 11
