import show_calendar field from CB for code studio Script objects

[davidsbailey]

Depends on code-dot-org/curriculumbuilder#324. Finishes PLAT-245.

Testing story

Manually verified:

1. No changes to coursea-2020 unit after being imported (show_calendar: false)
2. show_calendar is true after importing csd3-2020:

[development] dashboard > u = Script.find_by_name('csd3-2020')
[development] dashboard > u.show_calendar
=> true

If you save a script that has been updated with show_calendar it will clear the value if we don't add an input on the script edit page to keep it populated. This will get better with what I'm working on but figured its worth pointing out

Great catch Dani! To fix that, I think I'd need to either:

1. update the script DSL logic to handle this, or
2. wait until PLAT-460 is fixed, which seems like it should make the problem go away

I'll add a launch-blocking task to make sure this field is not getting wiped out on script save once PLAT-460 is done: https://codedotorg.atlassian.net/browse/PLAT-519

Does it need to go in the .script file though so that it would be seeded across environments or are we not worrying about that until we doing the seeding work? In any case I think its probably fine for it not to block this and to have PLAT 519 as a reminder that we need to follow up. I think adding the field on the Script Edit page is really a small work item so I'd be happy to take it after this ships
