feat: Add e2e label trigger for pull requests

* Add pull_request labeled event trigger
* Add condition to run only if label is 'e2e'
* Update workflow name to include label trigger
* Remove deprecated run-gha-workflow.yaml file

The workflow will now be triggered on schedule, workflow_dispatch,
and when a pull request is labeled with 'e2e'. This allows running
E2E tests on demand for specific pull requests. The `if` condition
ensures that the job only runs when the label is present, preventing
unnecessary runs on other pull request events.
The deprecated file that does the same as this changes
`run-gha-workflow.yaml` has been removed.
