Remove cloud trait for license factory
What does this MR do?
It may conflict when a factory is calling cloud
as an attr: https://gitlab.com/gitlab-org/gitlab/-/blob/979a9ab2d937953ef834a9a36cdf1250334c6116/ee/spec/factories/licenses.rb#L59. For example, some of the tests in !59107 (merged) failed because of that reason.
Since it's used in one place, let's remove it.
