Add check of invalid label in rescue

[whywaita]

fixes: #228

• We check labels in the rescue job.
  • The myshoes don't rescue a job that was not generated by myshoes.
• We always add the dependabot label.
  • This change supports https://docs.github.com/en/code-security/dependabot/maintain-dependencies/managing-dependabot-on-self-hosted-runners

Summary (generated)

This pull request refactors label-checking logic to improve code reusability and maintainability. The key changes include introducing a new utility function IsRequestedMyshoesLabel in the pkg/gh/label.go file and replacing duplicate label-checking logic with calls to this function across the codebase.

Refactoring and code reuse:

• Added the IsRequestedMyshoesLabel function in pkg/gh/label.go to encapsulate the logic for checking if a job has appropriate labels (myshoes, self-hosted, or dependabot).
• Replaced the inline label-checking logic in pkg/web/webhook.go with a call to the new gh.IsRequestedMyshoesLabel function, removing the redundant isRequestedMyshoesLabel function. [1] [2]

Functional changes:

• Updated the enqueueRescueRun function in pkg/starter/starter.go to skip rescue jobs without the required labels by using the new gh.IsRequestedMyshoesLabel function. This adds logging for skipped jobs.

Minor adjustments:

• Removed unused githubURL variable in pkg/starter/scripts.go and adjusted related code for label handling. [1] [2]

Pull Request Overview

This pull request refactors label-checking logic to improve code reusability and adds validation to prevent rescuing jobs not generated by myshoes. The changes extract duplicate label validation logic into a centralized utility function and ensure the system always adds the "dependabot" label for compatibility.

• Extracts duplicate label-checking logic into a reusable IsRequestedMyshoesLabel function
• Adds label validation to the rescue job process to skip jobs without appropriate myshoes labels
• Updates runner setup to always include the "dependabot" label regardless of GitHub URL configuration
