Add return ID to CRUD tools

[mattdholloway]

This pull request updates the MinimalResponse struct to include an ID field alongside the existing URL field. This change ensures that all minimal responses now return both the unique identifier and the URL for created or updated resources, making it easier for clients to reference resources directly.

• Added an ID field to the MinimalResponse struct in pkg/github/minimal_types.go, allowing API responses to include both the resource ID and URL.
• Updated all relevant API handlers (CreateGist, UpdateGist, CreateIssue, UpdateIssue, CreatePullRequest, UpdatePullRequest, CreateRepository, ForkRepository) to set the ID field in their minimal responses. [1] [2] [3] [4] [5] [6] [7] [8]
