The built in GitHub MCP Server is not loaded in `-p` mode

Description

➜  sweagentd git:(main) ✗ copilot -p "show me the 10 most recent issues in cli/cli repo"
● I'll fetch the 10 most recent issues from the cli/cli repository using the GitHub CLI.

Get 10 most recent issues from cli/cli repo
   $ gh issue list --repo cli/cli --limit 10 --json number,title,state,createdAt,author --jq '.[] |
   "\(.number) | \(.state) | \(.createdAt) | @\(.author.login) | \(.title)"'
   Permission denied and could not request permission from user
● Let me try without authentication by using the API directly:

Fetch 10 most recent issues from cli/cli using GitHub API
   $ curl -s "https://api.github.com/repos/cli/cli/issues?per_page=10&sort=created&direction=desc" |
    jq -r '.[] | "#\(.number) | \(.state) | \(.created_at) | @\(.user.login) | \(.title)"'
   Permission denied and could not request permission from user
● I don't have permission to access the network or the GitHub CLI with authentication. You'll need
    to run this command yourself:

This should be using the MCP server. If you check the logs with --log-level all, you will see that the GitHub MCP server is not being provided at all.

This should now be fixed, and I see that being the case on the latest copilot:
