Remove broken total count from workflow version (#20324)

## Problem

Opening a workflow run with a form step in the side panel, closing the
form and reopening it crashes the app: `<SidePanelWorkflowStepInfo>`
blows up on `workflow.versions.find` because `versions` is `null` in the
Apollo cache.

## Root cause

`useWorkflowVersion` was selecting:

```ts
workflow: { id, name, statuses, versions: { totalCount: true } }
```
Twenty's GraphQL field generator doesn't support connection-level
scalars — { totalCount: true } is interpreted as fields on the inner
WorkflowVersion node, gets filtered out, and the query collapses to:
versions { edges { node { __typename } } }
The server returns versions: null for that empty-node selection. 

Why now
The selection has always been wrong, but two recent changes made it
consistently surface:

Apollo Client v4 upgrade (#18584): stricter normalized writes, null
always wins.
#20242: WorkflowRunSSESubscribeEffect in the form filler keeps SSE
flowing, which re-fires useWorkflowVersion more often, making the bad
query consistently the last writer.
