Store Job in Entity

AsyncTasks are considered to be running until their token is passed to the sendTaskSuccess or sendTaskFailure api.

We will store the task's token in our approvalJobs entity so that we can complete the task later.

Update the task handler in wait-for-approval to store the approval job and it's token:

import { asyncResult, task } from "@eventual/core";
import { approvalJobs } from "./approval-jobs.js";

export const waitForApproval = task(
  "waitForApproval",
  async (input: { jobId: string; description: string }) => {
    return asyncResult<boolean>(async (token) => {
      // we'll use the job ID as the unique ID
      await approvalJobs.put(input.jobId, {
        taskToken: token,
        description: input.description,
      });
    });
  }
);
