   This PR modifies the modal for triggering a single DAG run manually, adding 
two fields:
   * Data interval start
   * Data interval end
   
   Those fields default to the current minute, rounded (and start = end), which 
seem to be the default value based on my testing.
   
   I added a client-side check to make sure that the start date cannot be set 
after the end date.
   
   **Reasoning behind this change**
   * `data_interval_start` and `data_interval_end` are optional when making the 
API call, and I assume that the backend infers it somehow. This is not 
transparent to the user, I think it would be better UX if the user can see and 
alter the data interval that will be used when triggering a DAG
   * There is a comment in 
[here](https://github.com/apache/airflow/blob/main/airflow-core/src/airflow/models/dag.py#L145)
 that seems to infer that the data interval should always be defined when DAGs 
are automatically scheduled. If it is the case, it would make sense to have the 
same requirement for manual triggers.
