Default github mcp server toolset not included by default #4436

Describe the bug

The github mcp server has a default toolset called 'default', however, it does not seem to be enabled by default.

Affected version

GitHub Copilot CLI 1.0.79

Steps to reproduce the behavior

Open copilot cli
use /mcp show on the built-in github mcp server
See it is missing permissions

Expected behavior

I expect the above list to be same as the list when using the default mcp server toolset
