autoUpdate in config.json is ignored

[czf]

Describe the bug

I think starting with 1.0.4 the auto-update setting in config.json is no longer working.

Affected version

1.0.4

Steps to reproduce the behavior

1. start with 1.0.3
2. update config.json to have
   "auto_update": false,
   "autoUpdate": false,
3. start copilot version stays at 1.0.3
4. manually update to 1.0.4
5. start copilot and version is automatically updated latest

Expected behavior

version stays at specific version

Additional context

windows
x86_64
Windows Terminal

the --no-auto-update still works
the COPILOT_AUTO_UPDATE environment variable set to false still works
