Close #72, add depends on as valid key

[plocket]

My mistake, I can close. My workflow has been failing, though:

Hmm, I see this is already present. Tests on my ALKilnSetup repo have been failing with depends on. https://github.com/SuffolkLITLab/docassemble-ALKilnSetup/actions/runs/31503848240/job/93820338136#step:3:509

User error, apologies!

Just to have this explicitly noted, it looks like it was failing because the interview had depends_on, instead of depends on. Might be worth a "did you mean ..." for certain issues like that, just to make it clear to folks what the correct wording should be
