fix(docker): pin netcat-openbsd version in Dockerfile.temporal

- Updated the Dockerfile.temporal to pin the netcat-openbsd package to version 1.217-r0. This change ensures consistency in the build environment and prevents potential issues with future updates.

Additionally, modified the error handling in index.ts to check for 'NotFoundError' when describing the workflow, improving the robustness of the scheduling logic.

These changes enhance the stability and reliability of the Temporal worker setup.
