The `azure-identity-perf` pipeline should not run when a code change is made to Azure::Core.

It looks like the triggers for the identity perf pipeline need to be fixed. They are being triggered on unrelated changes to core. We don't expect this identity perf pipeline to run in CI in this case.

This perf-tests.yml was introduced here: https://github.com/Azure/azure-sdk-for-cpp/pull/5373 https://github.com/Azure/azure-sdk-for-cpp/blob/7025e232bd9099f10f5992084e822366d084d454/sdk/identity/azure-identity/perf-tests.yml#L1-L9

See this for example: https://github.com/Azure/azure-sdk-for-cpp/pull/5420

According to the core ci.yml, only cpp - core - ci should run. But we are also seeing cpp - identity - perf, in particular cpp - identity - perf (Perf Linux).

What's missing in the yml definition?
