Implement LocalRepoOperator and RemoteRepoOperator classes

[codegen-sh]

This PR implements the LocalRepoOperator and RemoteRepoOperator classes that extend the base RepoOperator class. These classes provide specialized functionality for working with local and remote Git repositories.

Changes

New Classes

• LocalRepoOperator: A specialized implementation for working with repositories that are already on the local filesystem
• RemoteRepoOperator: A specialized implementation for working with repositories hosted on GitHub or GitHub Enterprise

Unit Tests

• Added unit tests for both new classes to ensure proper functionality

Implementation Details

• Both classes extend the base RepoOperator class
• LocalRepoOperator includes a from_repo_id class method for creating instances from database repository IDs
• RemoteRepoOperator overrides the remote_git_repo property and setup_repo_dir method to provide specialized behavior

These implementations should help standardize how repository operations are handled throughout the codebase and provide a cleaner interface for working with different types of repositories.
