PR Summary

• Updated CI/CD Workflow Trigger
  The event that initiates our continuous integration/continuous deployment (CI/CD) workflow has been updated. Now, any pushes to the "1.7.x" branch will trigger this workflow instead of the old "1.6.x" branch. This update ensures that our workflow reflects our latest production code.

• Expanded PHP Version Support for Linting Job
  The code linting job, which checks our code for errors, now includes the new PHP version "8.2". This addition aids in keeping our code compatible with recent PHP versions and increases our chances of catching potential issues early.

• Broaden PHP Version Scope for Unit Tests
  The job responsible for running unit tests, small tests that check individual parts of our code, has been updated to support both "7.4" and "8.0" PHP versions. This expansion ensures that our code stays robust and functions as intended across multiple PHP environments.
