Update stock data so that new records are added in batch_2

The record key is  "{stock name}_{date} {hour}". We have the data from 9:30-10:29 in batch_1 and batch_2 contains data from 10:30-10:59. This means that no new records are introduced, and therefore, only updates occur when ingesting batch_2. This makes validation of the data take too long for our testing. Proposed solution is to move the data from 10:00-10:29 into batch_2 so that we will have updates and inserts in both files
