oneoff script to remove lesson descriptions from scripts.en.yml

[davidsbailey]

Step 6a for PLAT-1528. Depends on #46188.

This PR adds a oneoff script which will be run on levelbuilder to remove unneeded lesson fields from scripts.en.yml, specifically: key, description_student and description_teacher. I am doing it this way rather than just making the change to scripts.en.yml in my PR in hopes of avoiding merge conflicts.

$ wc -l dashboard/config/locales/scripts.en.yml

after

$ wc -l dashboard/config/locales/scripts.en.yml
   25578 dashboard/config/locales/scripts.en.yml

Testing story

take a look at e4684c1 to see the results of running this script on my local machine. unfortunately, because scripts.en.yml is so big, you will have to look at the diff on your local machine. after diffing this locally, I inspected it to make sure that only the fields specified above were being removed.

Based on our conversation here: #46188 (comment), my understanding is there are still scripts in production relying on these strings.

[davidsbailey]

Not sure if this got resolved during stand up, but my understanding is that we are no longer using these strings as of #46143 . lmk if you want to jump on a call to discuss!

[dmcavoy]

I don't think its blocking but wondering if it would be safer to make sure we are on levelbuilder or local when running this script

[davidsbailey]

good call -- done!

[davidsbailey]

I reran it and confirmed that it still works in local development.

A misunderstanding on my part. Thanks for clarifying

[davidsbailey]

for deployment strategy, I am thinking:

1. wait for this to be deployed to levelbuilder
2. wait for 1-2 days of LB content scoops. confirm that none of them touch lines containing description_student or description_teacher
3. run the script on levelbuilder. commit the resulting changes to scripts.en.yml in its own commit
4. in the unlikely event that this causes a production problem, you could try reverting that one commit (or, due to merge conflicts, more likely resetting to just before that one commit).

I can just plan to do this when I am back, but if there is reason to move forward on this sooner, it could be done in my absence.

just noting that this has been confirmed for the 4 most recent content scoops, which are all of the scoops since #46188 reached levelbuilder.
