chore(graphql): [#65186] add date arguments to roles filter

This commit adds `from_date` and `to_date` to the seeded `it_system`
filter for the `roles` field resolver on `itsystems`.

While it is not strictly necessary right now, it is added to ease the
migration to consistent filtering in the future.
