Fix "Push and create PR" button sending wrong query

[rbren]

Description

This PR fixes an issue where the "Push and create PR" button was sending the wrong query. The button was supposed to send a query to create a pull request with a meaningful branch name, but it was sending the query associated with "Push to Branch" instead.

Changes

• Updated the ActionSuggestions component to ensure each button sends the correct query
• Made the code more explicit by directly using the string values instead of relying on the value parameter
• Fixed linting issues by removing unused parameters and formatting the code properly
• Refactored the code to reduce duplication by:
  • Creating a ButtonConfig interface to define button configurations
  • Extracting button configurations into constants
  • Adding a helper function to handle button clicks consistently
  • Improving code maintainability and readability
