### What problem does this PR solve?
Fixes the `AttributeError: 'bool' object has no attribute 'items'` error
when updating the `enabled` parameter of a document via the Python SDK
(Issue #11721).
Background: When calling `Document.update({"enabled": True/False})`
through the SDK, the server-side API returned a boolean `data=True` in
the response (instead of a dictionary). The SDK's `_update_from_dict`
method (in `base.py`) expects a dictionary to iterate over with
`.items()`, leading to an immediate AttributeError during response
parsing. This prevented successful synchronization of the updated
`enabled` status to the local SDK object, even if the server-side
database/update index operations succeeded.
### Type of change
- [x] Bug Fix (non-breaking change which fixes an issue)
### Additional Context (optional, for clarity)
- **Root Cause**: Server returned `data=True` (boolean) for `enabled`
parameter updates, violating the SDK's expectation of a dictionary-type
`data` field.
- **Fix Logic**:
1. Removed the separate `return get_result(data=True)` in the `enabled`
update branch to unify response flow.
2.
- **Backward Compatibility**: No breaking changes—other update scenarios
(e.g., renaming documents, modifying chunk methods) remain unaffected,
and the response format stays consistent.
