Add tracking by image download type

[jlin95]

Extended heap tracking event with the image download type.

Would have liked to add tests in this iteration but couldn't run tests for FE, see thread: https://boxwise.slack.com/archives/CB1UYDGLU/p1724450618067419?thread_ts=1724361187.607409&cid=CB1UYDGLU - will definitely add tests when I can address this.

Hey @HaGuesto, I did that when I did local testing. Do you need me to modify the getHeap function further to include extra logging?

I can't merge this PR, so you'd need to merge it or someone else @HaGuesto :) (It says The base branch restricts merging to authorized users.)
