chore: add minimal dependabot config for auto dependency updates

[Eeshu-Yadav]

This PR adds a minimal .github/dependabot.yml configuration to enable automatic dependency updates for:

• Rust (Cargo) dependencies

• GitHub Actions workflows

• Groups related dependencies to reduce PR noise

• Runs weekly and limits open PRs for easier review

This will help keep dependencies up-to-date and improve project security and maintainability.

Summary of Changes

Hello @Eeshu-Yadav, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a new Dependabot configuration file to automate dependency updates for both Rust (Cargo) dependencies and GitHub Actions workflows. The primary goal is to enhance project security and maintainability by ensuring dependencies are kept up-to-date with minimal manual intervention. The configuration is set to run weekly, with limits on open pull requests and intelligent grouping of related dependencies to streamline the review process.

Highlights

• Dependabot Configuration: Introduces a new .github/dependabot.yml file to enable automated dependency updates for the repository.
• Rust (Cargo) Dependencies: Configures Dependabot to check for updates to Rust (Cargo) dependencies weekly, with a limit of 5 open pull requests at a time. It also groups related dependencies like Tokio, Hyper, Tower, Futures (async-ecosystem), Prost, Tonic (protobuf-ecosystem), and Serde (serialization) to reduce PR noise.
• GitHub Actions Workflows: Sets up Dependabot to update GitHub Actions workflows weekly, limiting open pull requests to 3.

Code Review

This pull request introduces a Dependabot configuration for Rust and GitHub Actions, which is a great step towards keeping dependencies up-to-date and improving security. The configuration is well-structured, using groups to reduce pull request noise. I've suggested adding a couple more groups for tracing and rustls dependencies to further improve the organization of dependency updates. Overall, this is a valuable addition to the project.

[gemini-code-assist]

This is a good set of groups for dependency updates. To further reduce PR noise and keep related dependencies together, consider adding groups for the tracing and rustls ecosystems, which are also used in this project. This will make reviewing dependency updates even easier.

    groups:
      async-ecosystem:
        patterns:
          - "tokio*"
          - "hyper*"
          - "tower*"
          - "futures*"
      protobuf-ecosystem:
        patterns:
          - "prost*"
          - "tonic*"
      serialization:
        patterns:
          - "serde*"
      tracing-ecosystem:
        patterns:
          - "tracing*"
      rustls-ecosystem:
        patterns:
          - "rustls*"
