[Bug] TC-ACE-1.5 - Test Case YAML Script Needs to be Removed from V1.4 Branch

[Rajashreekalmane]

Describe the Issue:

The test case TC-ACE-1.5 appears in both the FirstChipToolSuite (semi-automated) and the Python Testing Suite in Test Harness (Version: v2.12-beta3+spring2025, Sha: 729573d). However, this test case is validated using a Python script, not an Yaml script.

The YAML script for TC-ACE-1.5 should be removed/deleted from the FirstChipToolSuite in the V1.4 branch to avoid redundancy and incorrect test execution.

Yaml script repo: The test case was not found in the expected directory:

Python script repo: The test case is available here:
🔗 [Python Testing Suite - TC_ACE_1_5.py](https://github.com/project-chip/connectedhomeip/blob/v1.4-branch/src/python_testing/TC_ACE_1_5.py)
