"removeDefinitions" vs. "removedDefinitions"

While the schema has "removedDefinitions" (past tense, with "d"):

https://github.com/clearlydefined/service/blob/70b5362d448ec16e4b21a0ffabf57ab93f5d0701/schemas/swagger.yaml#L96-L97

The test code has "removeDefinitions" (imperative):

https://github.com/clearlydefined/service/blob/70b5362d448ec16e4b21a0ffabf57ab93f5d0701/test/providers/curation/github.js#L147

I guess this is again a case where the schema is wrong.

BTW: Is somewhere documented what setting `removeDefinitions` to `true` does *exactly*? I can guess from the name that is removes past contribution patches, but does it remove *all* of them? Or just the latest one? Or can we limit the removal to particular revisions?
