Similar to what we did for mapped tasks, this pr uses stacked cards to show
primary and secondary states of task groups, making it easier to spot groups
with mixed task states.

The DAG:
```python
import time
from datetime import timedelta
import pendulum
from airflow.sdk import DAG, TaskGroup, task
QUICK = 0
SLOW = 60
@task
def work(sleep_seconds: int) -> None:
time.sleep(sleep_seconds)
@task
def check(should_fail: bool) -> None:
if should_fail:
raise RuntimeError("Failing on purpose to show failed cells in the
Grid view")
with DAG(
dag_id="task_group_grid_states",
schedule=None,
start_date=pendulum.datetime(2024, 1, 1, tz="UTC"),

work.override(task_id="quick_0")(QUICK)
