Support Generic Git Remotes (Not Just GitHub)

Summary Currently, the project only supports pushing to GitHub. This limits users who work with GitLab, Bitbucket, or self-hosted Git servers.

Request Refactor the Git remote logic to support any Git provider by allowing users to configure: • Remote URL (HTTPS or SSH) • Username/org • Auth method (token/key)

Contributing I would like to implement this feature ! Since the project already uses standard Git libraries, the change mainly involves removing GitHub-specific assumptions(Such as the hard coded GitHub urls) and making the Git remote configurable.
