Write a python code that would read the below file if titled (commit_activity.json), loop through each option the highest "total" value, and then printing that week's "week" value in epoch timestamp. Or esentially finding what week had the greatest number of commits (after days its ordered as days starting at sunday and the total is the total number of commits which I need the highest of. The answer should be 6 since We can see it, and I want it to return the value after "week"
