Add time delta option when searching for deutsche_bahn connections (#24600)

Browse source 
* Add time delta option when searching for connections

Add another option 'in' to search for upcoming connections in the future.
Handy if you need a few minutes to get to the train station and need to add that to the queried departure time.

* correct style errors

* rename new option

* rename new option (2/2)

* add offset correctly
