feat: Repository specific runners

[jribble]

This feature adds an optional github_repository variable. When this variable is specified runners will be created on the repository. When it's not specified runners will be created on the organization.

It might be a good idea to add to the documentation that the Github App should be scoped to the repository if the runners are repository specific.

Pull Request Overview

This PR introduces an optional github_repository variable to allow runners to be created at the repository level instead of the organization level, updates Terraform modules and the runner registration script to use a conditional registration URL, and enhances the GitHub controller logic to call the correct API endpoints based on that variable.

• Added github_repository variable in root and module variable definitions
• Computed registration_url in custom-data and updated the user-data script to use it
• Refactored GitHub controller to request tokens and list runners on either repos or orgs, and updated documentation

• Add a default value (e.g., "") to the new github_repository entry in the README table so it matches the other variable definitions.

| <a name="github_repository"></a> [github\_repository](#github\_repository) | GitHub repository for repository specific runners. If blank runners will be created for the organization. | `string` |

variables.tf:71

• [nitpick] Consider adding a description attribute to the github_repository variable to clarify its purpose, following the pattern of other variables.

variable "github_repository" {

app/runner-controller/github.js:45

• Add unit tests covering both repository-specific and organization-specific branches in createRegistrationToken and listGitHubRunners to verify correct API endpoint selection.

Thank you for the contribution @jribble sorry we left this in limbo for so long.

Unfortunately we have decided to archive this repository for the time being. We have shifted attention to other projects and this project is not getting the love and attention it deserves.
