Enhance update script to allow user input for n8n worker count

Browse Source 
- Added functionality to prompt the user for a new n8n worker count during the update process, including validation for positive integers.
- Improved error handling and logging for cases where the N8N_WORKER_COUNT line is missing in the .env file, ensuring better user guidance and script robustness.
