Possible additional changes to be added to PR #100

[aivarsoo]

Following up on the PR #100. I additionally propose to make the following changes:

1. Replace the classes Goal0, Goal1 and Goal2 etc (all the navigation tasks) with the config dictionaries.
2. Perform similar changes in the vision environments relying on the Builder class.
3. Store the task name in the config dictionary for all tasks in the navigation environments. This will simplify the environment creation process in the Builder class, i.e., there will be no need for the get_task_class_name method. This will also potentially allow to register just one base environment for customization streamlining the process. The code will be

env = safety_gymnasium.make('SafetyNavigation-v0', config={'agent_name': ..., 'task_name': ..., }

Please let me know if this is aligned with the library development and makes sense to implement
