Migrate GitHub teams to infrastructure-as-code

- Add 25 teams with proper hierarchy (steering-committee, SDK teams, working groups, interest groups)
- Add 67 team members with their assignments
- Add repository access configuration for all 21 repositories
- Refactor github.ts to use config-driven approach with repoAccess.ts
- Mark all MCP teams as GitHub-only with onlyOnPlatforms
- Use RepositoryCollaborators for authoritative access management

Note: GitHub Projects V2 permissions are not yet supported by Pulumi and must be managed manually. See pulumi/pulumi-github#1006
