Code Review

This pull request introduces a Dependabot configuration to automatically manage pip and GitHub Actions dependencies. The configuration is well-formed and functional. I've added a suggestion to enhance it by including standardized commit message prefixes and labels for the pull requests generated by Dependabot. This will improve the maintainability and traceability of dependency updates.

[gemini-code-assist]

This is a great start for setting up Dependabot. To further improve maintainability and the clarity of your git history, consider adding a standard prefix to the commit messages for dependency updates using the commit-message option. It's also helpful to add labels to automatically categorize these pull requests, making them easier to track.

  - package-ecosystem: "pip"
    directory: "/"
    schedule:
      interval: "weekly"
    commit-message:
      prefix: "chore(deps)"
      include: "scope"
    labels:
      - "dependencies"

  - package-ecosystem: "github-actions"
    directory: "/"
    schedule:
      interval: "weekly"
    commit-message:
      prefix: "chore(deps)"
      include: "scope"
