Update workflow nodes configuration (#6861)

- Improve the design of the right drawer
- Allow to update the trigger of the workflow: the object and the event
listened to
- Allow to update the selected serverless function that a code action
should execute
- Change how we determine which workflow version to display in the
visualizer. We fetch the selected workflow's data, including whether it
has a draft or a published version. If the workflow has a draft version,
it gets displayed; otherwise, we display the last published version.
- I used the type `WorkflowWithCurrentVersion` to forward the currently
edited workflow with its _current_ version embedded across the app.
- I created single-responsibility hooks like
`useFindWorkflowWithCurrentVersion`, `useFindShowPageWorkflow`,
`useUpdateWorkflowVersionTrigger` or `useUpdateWorkflowVersionStep`.
- I updated the types for workflow related objects, like `Workflow` and
`WorkflowVersion`. See
`packages/twenty-front/src/modules/workflow/types/Workflow.ts`.
- This introduced the possibility to have `null` values for triggers and
steps. I made the according changes in the codebase and in the tests.
- I created a utility function to extract both parts of object-event
format (`company.created`):
