(#2986) Strip config list down to just config

[vexx32]

Description Of Changes

• Remove deprecation messages regarding config list as they are no longer relevant
• Remove non-config-related output from the config command and service.

Motivation and Context

We have other commands for listing features, sources, apikeys, etc. Config can finally just be config. Long-awaited deprecation.

Testing

1. Build and run with config list
2. Ensure only config values and nothing else is listed
3. Run ConfigCommand tests and ensure nothing breaks

Operating Systems Testing

Tested on Win11

Change Types Made

• Bug fix (non-breaking change).
• Feature / Enhancement (non-breaking change).

Change Checklist
