### Apache Airflow version

2.6.3

### What happened

TimeSensor and TimeSensorAsync convert timezones differently.

TimeSensor converts a naive time into an tz-aware time with `self.dag.timezone`. TimeSensorAsync does not, and erronously converts it to UTC instead.

### What you think should happen instead

TimeSensor and TimeSensorAsync should behave the same.

### How to reproduce

Compare the logic of TimeSensor versus TimeSensorAsync, given a DAG with a UTC+2 (for example `Europe/Berlin`) timezone and the target_time input of `datetime.time(9, 0)`.
