Remove educator searchbar precomputing from nightly task
Remove educator searchbar precomputing from nightly task

+ @jhilde had the right idea about this from the beginning; this should run as its own nightly task
+ The educator searchbar precomputing sometimes takes more than 20 hours to run for reasons we don't fully understand yet
+ That throws an import error email which is high-urgency; put precomputing this JSON to optimize the searchbar endpoint is not high-urgency because it doesn't block educator login. So this should get its own, less urgent error report.
