Add RepositoryInfo Class for Benchmark Repository and Team Details

This commit introduces the RepositoryInfo class, designed to encapsulate details about the repository and team associated with a benchmark run.

The class includes the following fields:
- repoUrl: The URL of the repository where the benchmark code resides.
- teamName: The name of the team responsible for the benchmark.
- benchmarkGitCommitSha: The Git commit SHA for the benchmark code.
- agentGitCommitSha: The Git commit SHA for the agent code.

The class supports JSON serialization and deserialization, making it easy to use with Flutter's JSON handling mechanisms.
