Backend runtime upgraded to Node.js v20.18 in self-hosted Retool 3.163

The backend runtime in self-hosted Retool 3.163 and later has been upgraded to use Node.js v20.18. This change may result in memory and CPU usage of containers to increase. Without sufficient resources, this could impact the performance of Retool Workflows. If necessary, you can increase the memory limits for workflows using the WORKFLOW_MEMORY_LIMIT_MBS environment variable.
