fix: Add missing tagged_builds parameter to Actor update method (#596)

Add support for the missing `tagged_builds` parameter in the Actor
update method, allowing users to create, update, or remove build tags.

The parameter accepts a dictionary mapping tag names to either:
- A dict with 'build_id' key to assign/reassign a tag
- None to remove a tag

**Example usage:**
```python
client.actor('my-actor').update(
    tagged_builds={
        'latest': {'build_id': 'abc123'},
        'beta': None  # removes beta tag
    }
)
```

**Changes:**
- Added `tagged_builds` parameter to `get_actor_representation()` helper
function
- Added `tagged_builds` parameter to `ActorClient.update()` (sync
version)
- Added `tagged_builds` parameter to `ActorClientAsync.update()` (async
version)
