Review Comment:
Please add a test case for nested task group
It's important to test how this behave when `max_active_groups_per_dagrun=1`
and the code has task group inside task group:
```
with TaskGroup(group_id='group1') as tg1:
...
with TaskGroup(group_id='group2') as tg2:
...
```
We need to make sure it doesn't cause deadlock.
