remove the workaround for no-misused-promises as it broke lambdas execution

[Amplifiyer]

Problem

After the recent change of #2438, health checks are failing as lambda execution is failing with error

"TypeError [ERR_INVALID_ARG_TYPE]: The \"callback\" argument must be of type function. Received undefined",
        "    at setInterval (node:timers:212:3)",
        "    at file:///var/task/index.mjs:1:1769",
        "    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)"

I tried changing it to use IIFE as well and then instead I got the following error from lambda

  "TypeError [ERR_INVALID_ARG_TYPE]: The \"callback\" argument must be of type function. Received an instance of Promise",
        "    at setInterval (node:timers:212:3)",
        "    at file:///var/task/index.mjs:1:1769",
        "    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)"
