Doc changes

1. Rolled back two changes from #7763:

   1. Re added "identifiers" in this docstring, as the sentence is incomplete currently.

      - Defines the of each GBuffer texture (See the method 
      + Defines the identifiers of each GBuffer texture (See the method 
      

   2. Removed the accidentally re added reference to the removed carla.Sensor.is_listening property. See #7439

2. fixes of spelling mistakes (docstring and documentation)

3. Corrected wrong literal wrapping instead of linking in

[old:] Defines the of each GBuffer texture (See the method [carla.Sensor.listen_to_gbuffer](#carla.Sensor.listen_to_gbuffer)).

5. Added Missing __init__ documentation for OpendriveGenerationParameters
6. Client.replay_file: replay_sensors was not declared as default value
7. World.[try_]spawn_actor parameter is named attachment_type and not attachment
8. Added documentation for Transform.inverse_transform from #7999
9. added WorldSnapshot.elapsed_seconds to API description.
10. Fixed missing/wrong parameter for Client.apply_batch[_sync]

Needs decision:

• [ ] TrafficManager.set_boundaries_respawn_dormant_vehicles has no default values. Current default values are annotations that describe the bounds but are not really default values. I am not sure how to address this.

Changes in non-documentation files:

1. Added space after # Heading when docs are generated #Python API references -> # Python API references to be correct markdown. I am not sure if this is intentionally or an old oversight, but haven't seen anything where this could be relevant
2. Changed in python examples: on_world_tick(self, timestamp -> world_snapshot) to better reflect correct API usage.

Where has this been tested?

• Platform(s): Ubuntu
• Python version(s): 3.7 & 3.10 (should be irrelevant)
• Unreal Engine version(s): 4.26

Possible Drawbacks

• Does 4 have any side effects?

Concerning 11): Are there sideeffects to consider with the parameter renaming of def on_world_tick(self, timestamp -> world_snapshot): in the examples?

Note:

Currently pending changes to snippets and blueprint library (bp_libarary.md) from make PythonAPI.docs not included
