fix(server): stabilize app install version-gate integration test (#22826)

## Why

The `failing-app-installation-workspace-version` integration suite fails
on CI (e.g. [this
run](https://github.com/twentyhq/twenty/actions/runs/29105697459/job/86405891168)):

```
App requires Twenty server >=2.21.0 but this server is 2.20.0.
subCode: SERVER_VERSION_INCOMPATIBLE
```

The test uploads an app requiring `>=${TWENTY_CURRENT_VERSION}` and
expects the install to be rejected by the **workspace** version gate.
But after the `2.21.0` version bump, `TWENTY_CURRENT_VERSION` (`2.21.0`)
moved ahead of the latest instance upgrade command (`2-20`, so
`getInferredVersion()` returns `2.20.0`). The tarball upload runs the
**instance** server-compat check first, which rejects `>=2.21.0` against
a `2.20.0` server before the workspace gate under test is ever reached.

The sibling sync test is unaffected because sync only validates
workspace compatibility, not the upload-time instance check.

## What

Derive the required version range from the version the instance actually
reached (the workspace upgrade cursor via
`extractVersionFromCommandName`) instead of the drifting
`TWENTY_CURRENT_VERSION` constant. This way:

- The upload passes the instance server-compat check (server satisfies
`>=<current version>`).
- The workspace, which resolves one version behind after the injected
failed cursor, still fails the workspace gate, producing the expected
`WORKSPACE_VERSION_INCOMPATIBLE` error.

The error assertion keeps using the normalized snapshot
(`scrubSemverVersions`), so the concrete version numbers do not leak
into the snapshot and future version bumps won't churn it.
