Telemetry cache potentially not uploaded

> ### `az feedback` auto-generates most of the information requested below, as of CLI version 2.0.62

**Describe the bug**
It appears that this particular code: https://github.com/Azure/azure-cli/blob/dev/src/azure-cli-telemetry/azure/cli/telemetry/components/records_collection.py#:~:text=os.listdir(folder)-,if%20fn%20!%3D%20%27cache%27,-%5D
means that the telemetry 'cache' file content is omitted from uploading it into applicationinsights.
Apologies, if this is as intended by design, however it seems to not let me obtain (upload in applicationinsights) the cached information.

**To Reproduce**

Have telemetry switched on & see what data is available on applicationinsights (using the 'azure-cli-telemetry' package).

**Expected behavior**
All telemetry data is uploaded in applicationinsights.
