Code Review

This pull request updates the Workflows quickstart samples and tests to improve execution consistency and configuration. It switches to using ts-node/register for test execution, updates package dependencies, and adds cleanup logic to tests to ensure workflows are deleted after execution. My feedback highlights that the current error handling in the test suite is too broad, as it swallows all exceptions instead of specifically checking for 'Not Found' errors, and points out that the ts-node/register hook is unnecessary when executing plain JavaScript files.
