fix(rbac): ensure migration 0056 runs before 0010 removes group field (#21964)

fix(rbac): ensure migration 0056 runs before group field is removed

Migration 0010 removes the `group` FK from the Role model, but
migration 0056 (authentik_core) queries `group_id` on Role as part of
a data migration to move guardian permissions to RBAC roles.

When upgrading from 2025.x, Django's migration executor can schedule
0010 before 0056 because neither depends on the other — only 0056
depends on 0008. This causes a FieldError at runtime:

  Cannot resolve keyword 'group_id' into field.

Adding 0056 as a dependency of 0010 enforces the correct ordering:
the data migration that reads `group_id` must complete before the
schema migration that removes it.
