[permissions] fix workflows + remove shouldBypassPermissionChecks for system objects (#12559)

In this PR 

1. fix workflow step creation by adding forgotten
`shouldBypassPermissionChecks` in WorkflowVersionStepWorkspaceService
2. clarify the rule for twentyORMGlobalManager: do not add unnecessary
`shouldBypassPermissionChecks` for system objects (there are no
object-records permission checks on system objects, they are dealt with
at resolver level)
