copilot plugin marketplace remove command does not clean up settings.json

[pbiasotti-southworks]

Describe the bug

When running the command copilot plugin marketplace remove {your-markeplace} --force, the plugins from that marketplace are uninstalled

Affected version

GitHub Copilot CLI 1.0.45

Steps to reproduce the behavior

1. Install a plugin using copilot plugin install {your-plugin}@{your-marketplace}
2. Check $HOME\.copilot\settings.json and a new entry is added under enabledPlugins
3. Remove the marketplace and all the plugins with the command copilot plugin marketplace remove {your-marketplace} --force
4. Re-add the marketplace copilot plugin marketplace add {org}\{repo}
5. Check that $HOME\.copilot\settings.json entry was not removed
6. Open copilot and it will auto-install all the plugins in enabledPlugins

Expected behavior

The enabledPlugins property in the settings.json file should be removed to avoid auto-install
