Enhance PR Workflow with Integration Tests Using Kind Cluster

[ibakshay]

This pull request improves our testing process by introducing integration tests to the existing PR workflow. Key changes include:

1. Automated creation of a Kind cluster within the workflow to set up the integration test environment.
2. Execution of integration tests in the locally created Kind cluster.
3. Automated deletion of the Kind cluster upon workflow completion, ensuring clean-up of resources.

Awesome! What if a plugin does not provide chart tests? Does the workflow then fail?

No, the workflow won't fail. The chart tests will only run if the tests are there in the templates/tests folder.
