Set correct `package_name`

[jo-elimu]

Description

The values used as package_name is not correct: https://github.com/elimu-ai/ml-event-simulator/blob/main/lang-ENG/android-id-e387e38700000003/version-code-3001018/video-learning-events/e387e38700000003_3001018_video-learning-events_2024-10-22.csv

Why?

While ai.elimu.analytics is the Android app responsible for uploading the learning events from the device to the REST API, the value in the package_name column should be the package name of the Android app where the event originated, e.g. ai.elimu.filamu.
