`T.nilable` was removed from the `P7Zip#dependencies` type signature in a previous commit, as `UnpackStrategy#dependencies` doesn't allow for a nilable return type. This updates the type signature for the other `#dependencies` methods to also remove `T.nilable`, as they would produce a runtime error otherwise.
