Feature description

As a Dependabot user, when I configure groups for a particular (ecosystem, directory, target branch), I want to be able to add different labels to each group.

Proposal:

version: 2
updates:
  - package-ecosystem: npm
    directory: "/"
    schedule:
      interval: daily
    groups:
      version-updates:
        applies-to: version-updates
        labels:
          - version-update
        patterns:
          - "*"
      security-updates:
        applies-to: security-updates
        labels:
          - security-update
        patterns:
          - "*"

thanks @bdragon for creating feature request... I'd like to add the requirement from my customer which might help to address additional questions

My customer has a mono repo based on multiple programming languages such as Python, JavaScript and more... they would like to distinguish between version and security updates PRs...

I hope this feature request will support more programming languages such as Python, Java, dotnet and more

Thanks

We would also be interested in this in order to ignore certain groups from our autogenerated changelog 😊

# .github/release.yml
changelog:
  exclude:
    labels:
      - development
  categories:
    - title: Bug Fixes
      labels:
        - "bug"
    - title: Dependency Updates
      labels:
        - "dependencies"

# .github/dependabot.yml
version: 2
updates:
- package-ecosystem: pip
  directory: "/"
  schedule:
    interval: weekly
  groups:
    production-dependency-patches:
      dependency-type: "production"
      update-types: ["patch"]
    development-dependencies:
      dependency-type: "development"
      update-types: ["major", "minor", "patch"]
      labels:
      - development

If this is relatively trivial to implement, and you provide a bit of guidance on where this would have to be done, I'd be willing to give it a try 🙏

Thank you!
