feat: Add Copilot coding agent and content exclusion org endpoints

Implement support for two Copilot organization management endpoints
under the CopilotService.

- Add ListCopilotCodingAgentRepositories for
  GET /orgs/{org}/copilot/coding-agent/permissions/repositories.
- Add GetCopilotOrganizationContentExclusionDetails for
  GET /orgs/{org}/copilot/content_exclusion.
- Add tests covering both endpoints, JSON round-trip tests for the
  new types, and regenerate accessors and iterators.

API docs:
- https://docs.github.com/rest/copilot/copilot-coding-agent-management#list-repositories-enabled-for-copilot-coding-agent-in-an-organization
- https://docs.github.com/rest/copilot/copilot-content-exclusion-management#get-copilot-content-exclusion-rules-for-an-organization

Fixes: #4175
